Rainy Season Dangers for Dogs

Each year, certain parts of North America are bombarded with rain. While this may be good for the garden, high rainfall can potentially pose some real threats to your dog.

Mushrooms

During the rainy season, mushrooms may pop up in your yard with more frequency. There are thousands of species of mushrooms, but thankfully only about 100 are poisonous. That said, mushroom identification is very difficult, so it's hard to tell which are poisonous versus which are benign. As a result, whenever you see mushrooms growing in your yard, make sure to remove them immediately and throw them away to prevent accidental ingestion by your dog. If your dog does get into a mushroom, contact your veterinarian immediately about inducing vomiting to get any potential toxin out.

Certain types of mushrooms may cause organ injury including:

• Gastrointestinal injury (signs include drooling, not eating, vomiting, diarrhea)

• Liver linjury (signs include vomiting, black tarry stool, yellow skin)

• Kidney injury (signs include abnormal urination and thirst)

• Cardiovascular injury (signs include a very slow or rapid heart rate)

• Neurologic injury (signs include hallucinations, tremors, seizures)

When in doubt, get to your veterinarian immediately as it's easier - and less expensive - to treat early on versus once clinical signs have developed.

Leptospirosis

Leptospirosis, a bacteria-like spirochete, is carried naturally by wildlife, like rodents and raccoons. In high rainfall situations, it’s prevalent in the environment. In dogs that have exposure to water sources, contaminated by wildlife urine (puddles, streams, ponds, etc.), transmission can occur. Canine leptospirosis can result in liver injury and acute kidney injury.

Signs of leptospirosis include:

• Vomiting

• Not eating

• Malaise

• Yellow skin

• Excessive thirst

• Urination

As leptospirosis can accidentally be transmitted to humans, it's important to talk to your veterinarian about prevention, including vaccines.

Mosquitoes

While mosquitoes may seem like just a pesky insect to you, they can be life-threatening to your dog. That's because mosquitoes can carry Dirofilaria, which transmits heartworm infection to your dog. Thankfully, there is a very effective preventative in either a topical or oral form. When in doubt, use year-round control to prevent problems from mosquitoes. If your dog has thin fur or skin and is more predisposed to getting bitten, use a vet-approved topical insect repellent that repels mosquitoes or talk to your veterinarian to be safe before applying anything.

Toads and frogs

Depending on where you live in the United States, certain types of toads - specifically the Bufo marinus or Bufo alvarius - can be poisonous to dogs. In fact, a dog drinking water from an outside dog bowl, that had a poisonous toad sitting in it, can result in clinical signs of drooling, panting, walking drunk, a racing heart rate, a very slow heart rate, or even seizures. Frogs are not toxic, but can cause gastrointestinal upset when ingested.

To be safe, supervise your dog outside to prevent accidental ingestion of dangers like toads and frogs. When in doubt, contact your veterinarian or ASPCA Animal Poison Control Center at 888-426-4435 if you think your dog is ill or could have ingested something poisonous.

Dealing With a Shedding Dog

Dog shedding can be frustrating for all of us, no matter how much we love our dogs. The mess of dog hair can be enough to drive dog owners nuts. All dogs shed to some degree, with the exception of completely hairless dogs. Certain breeds (so-called hypoallergenic dogs) shed very little, while others (namely heavily double-coated breeds) shed large amounts.

Year-Round Shedding

All animals with hair shed on a regular basis. This is part of the natural life cycle of hair shafts within the follicles. All hair shafts go through phases of growth and shedding. The phases affect the rate of hair growth and will vary by breed, age, hormones, environment and overall health of the dog. These factors also contribute to the length and texture of the hair, though genetics is the predominant factor.

Dogs with continuously growing hair, like Poodles and Yorkshire Terriers, have hair shafts with longer life spans and shed very little. On the other hand, dogs like Labradors and Huskies have a shorter hair shaft lifespan and more abundant undercoats, resulting in greater shedding.

Shedding Season

In general, most dogs will shed extra during spring and fall. Most dogs have two coats; they have undercoats and top coats. The top coat is what you see and feel on the outside. The undercoat is made up of secondary hairs that grow around the primary hairs and tend to be shorter and softer. Seasonal shedding occurs as a result of temperature change. This process is sometimes called "blowing coat." When the weather warms, dogs shed their old winter undercoats to make way for a lighter summer coat. Then, when it begins to get cool again, dogs shed their lighter undercoats and grow thicker, warmer coats for winter.

Not all coat types are affected the same way by temperature changes. For example, dogs like Bichons and Shih Tzus have less undercoat, so they shed less when seasons change. The old coat must still be removed by grooming the dogs. However, dogs like Newfoundlands and Malamutes have heavy, thick undercoats that make shedding much more obvious. Basic brushing is important for both coat types.

Other Reasons for Shedding

Your dog's health can affect the shedding rate, so it is important to take note of unexplained excessive shedding. Skin problems, endocrine diseases, nutritional or vitamin deficiencies, and other metabolic disorders can cause hair loss or change the rate of hair growth. It is important to contact your veterinarian if the rate of shedding seems unusual for your dog. Keep your dog healthy with routine vet visits and proper nutrition. Contact your vet immediately if you notice any signs of illness.

Get Control Over Shedding

There's no way to completely stop shedding. It's a healthy and natural process that is necessary for dogs. Shaving your dog down is not a good idea, as it can interfere with your dog's natural self-cooling and self-warming mechanism. In the long run, it will not make shedding occur any less. In rare cases, the hair in shaved areas will grow back abnormally or not at all. The key to preventing excessive shedding is to keep up with it with brushing.

Routine grooming is absolutely essential for all dogs. Brushing or combing your dog helps to remove dead hairs before they can fall on your carpet, bedding, and upholstery. It will also prevent those dead hairs from forming mats on your dog's coat that can eventually harm the skin. Brushing also distributes the natural, healthy oils produced by the skin throughout the hair coat. Using the right grooming tools can make a great difference. For heavy shedders, a special shedding tool like the FURminator can work wonders. For some coat types, the dead hairs don't shed as much, but they cause the dog's coat to appear ragged and can eventually become matted. Some owners prefer to take these dogs to a professional groomer periodically for coat care. For some coat types, hand-stripping is a technique that is often preferred over trimming the dog's hair.

Managing the Aftermath of Shedding in Your Home

Shedding makes a mess, no doubt about it. As a dog owner, you have probably come to terms with the fact that regular house cleaning is the norm, especially during shedding season. The key is to remove hair before it has a chance to embed itself into your carpet and upholstery. Keeping a pet hair tape roller around for touch-ups throughout the day is an excellent idea.

For a deeper cleaning of upholstery and small areas, consider using a handheld vacuum designed to pick up pet hair, like the Dyson DC31 Animal. When it comes to cleaning carpets, Panasonic's Pet-Friendly JetSpin Cyclone does the job well. For non-carpeted floors, some excellent options include the Swiffer, the Fur-Be-Gone Broom, and similar style products.

Dog Eye Allergies: Symptoms and Treatment

If you notice that one or both of your dog’s eyes are red, you may be wondering what the cause could be.

Dogs with allergies more commonly show symptoms related to the skin or intestinal tract, but it is possible that allergies may be causing the irritation in your dog’s eyes—just like in people with seasonal allergies.

The medical term “allergic conjunctivitis” is used to describe inflammation of the eye that’s usually caused by environmental allergens like pollen and mold. Dogs with skin-based allergy symptoms (allergic dermatitis) are more likely to experience allergic conjunctivitis than dogs with no history of allergies.

If you believe that your dog is suffering from allergic conjunctivitis, it’s important to have them seen by a veterinarian to rule out other more serious diseases that can have similar symptoms.

Here’s what you need to know about dog eye allergies.

Symptoms of Dog Eye Allergies

In dogs, redness of the eyes is a vague symptom that can be caused by a wide variety of underlying diseases.

For allergic conjunctivitis, redness is usually seen in both eyes. You may also notice symptoms like:

• Squinting of the affected eye(s)

• Pawing at the face

• Discharge coming from one or both eyes

Dog Eye Allergies and Itchy Skin

If your dog has a history of itchy skin, it's worth mentioning to your veterinarian.

Dogs with itchy skin will more commonly experience allergic conjunctivitis than the general dog population.

Affected dogs are usually under 3 years of age when they first become symptomatic. Although all dog breeds have the potential to develop allergic dermatitis, common breeds with a predisposition for this condition include:

• Boxer

• Cocker Spaniel

• French Bulldog

• German Shepherd

• Golden Retriever

• Labrador Retriever

• Poodle

• West Highland White Terrier

How Do Vets Diagnose Dog Eye Allergies?

Although a test called “conjunctival cytology” may reveal inflammatory cells that will confirm a diagnosis of allergic conjunctivitis, the cells are not always present. As a result, many veterinarians will diagnose eye allergies through the process of elimination.

Your veterinarian may perform several brief tests to rule out diseases with similar symptoms, like eye infections, dry eye, or corneal ulcers. Other details, like your dog’s age, breed, and history of itchy skin, can also help point your veterinarian to this diagnosis.

In rare cases, a biopsy of the conjunctival tissue around the eyes—taken while your dog is under general anesthesia—may be needed to achieve a definitive diagnosis, or to rule out other, more serious causes of red eyes.

An emerging test called the conjunctival provocation test has shown promise as a quick and easy test to definitively diagnose allergic conjunctivitis. However, it’s currently not widely available and would likely be performed by veterinary dermatologists—not your general practice veterinarian.

What Can You Give Dogs With Eye Allergies?

In mild cases, simply flushing the eyes with sterile saline once or twice a day may be enough to remove the allergen and resolve the symptoms.

You should not use contact solution for this purpose.

Although antihistamines provide relief for people with eye-related allergies, antihistamines have a variable effect in dogs with this condition. Therefore, eyedrops containing steroids are often the treatment of choice for dogs with allergic conjunctivitis.

It’s important to note that steroid-based eyedrops can be very harmful to dogs with other, similar diseases in the eyes, so you should never start treatment without first consulting your veterinarian.

Severe cases may require the use of oral medications in addition to eyedrops.

Follow-Up Testing and Treatments

Generally, a recheck is recommended after one to two weeks of treatment so that your veterinarian can assess how well the medications have worked.

If minimal improvement is seen, it’s possible to be seen by a veterinary dermatologist, who can perform allergy testing and other diagnostics to uncover which allergens may be triggering your dog’s allergic conjunctivitis.

If possible, the allergens are removed, often by changing the diet. If removing allergens is not possible, your dog’s dermatologist may suggest immunotherapy for long-term treatment.

If the allergen can’t be removed or treated with immunotherapy, it is very likely that a dog with allergic conjunctivitis will experience flare-ups throughout her life. Fortunately, the symptoms caused by allergic conjunctivitis are fairly mild, and with proper treatment and management, affected dogs generally live long and happy lives.

Food Allergies in Dogs: Symptoms and Treatment

Dogs, like people, can have allergies to certain foods. In fact, food allergies are one of the most common allergic reactions known to affect our canine friends. When your dog is allergic to a particular food, their immune system responds to the food as it might respond to an infection or bee sting, producing antibodies that in turn cause the symptoms associated with the allergic response.

We all know dogs are “garbage guts” and will eat, well, a wide range of stuff. Sometimes it’s hard to distinguish a little upset stomach from an allergic reaction to food. When symptoms such as diarrhea persist, allergies may be the cause. These symptoms usually take time to develop, since your dog’s immune response takes time to produce the antibodies that cause the allergic response.

Symptoms of Food Allergies in Dogs

The most common symptoms of a food allergy are:

• Itching

• Hair loss

• Skin infection

Less common symptoms include:

• Vomiting

• Diarrhea

• Weight loss

• Lethargy

• Hyperactivity

Sometimes, dogs show more aggression because of their discomfort.

The most common foods that cause canine food allergies are proteins such as lamb, beef, chicken, and eggs. In addition, some dogs can be allergic to soy or gluten, which is found in wheat and similar grains. Some dogs may be allergic to preservatives or other food additives, as well.

When a dog eats a food they are allergic to, a vicious cycle occurs: they eat, their body produces an allergic reaction, and they become symptomatic, i.e., they itch, has diarrhea, or may vomit—which is why it is so important to identify the food for which they are having the reaction to. Frustrating, right?

Diagnosing Food Allergies in Dogs

If your veterinarian suspects your dog of having a food allergy, they will perform a thorough physical exam and take a detailed history of your dog’s food intake and activities. In addition, your veterinarian may recommend routine diagnostics to rule out other causes of your dog’s symptoms.

Your veterinarian will likely recommend a strict hypoallergenic diet trial for at least 2–3 months to see if it alleviates your dog’s symptoms. The suggested diet cannot contain any ingredients your dog has been recently eating; there are several specifically designed diets to help prevent food allergies. During the food trial, it is critical that your dog does not get any treats or supplements unless approved by your veterinarian.

Treatment for Dogs With Food Allergies

The best treatment for food allergies is avoidance. Once you’ve identified the food your four-legged friend is allergic to, you will be able to avoid it in the future and help your dog live an allergy-free life. Unfortunately, there is no way to prevent your dog from developing food allergies.

If you have questions about canine food allergies, please talk with your veterinarian—the best resource when it comes to the health and well-being of your best friend.

Tooth Root Abscesses in Dogs

Tooth root abscesses are infections that occur around the tooth root. They most commonly develop in the upper fourth premolar tooth, also known as the carnassial tooth. Once the infection develops around the root and between the skull bone, it is difficult for the body to fight infection in this location. As the infection builds, it often creates a draining tract through the skin on the cheek or below the eye. The skin is the weakest on this portion of the body in this area.

A classic sign of a tooth root abscess on physical examination is a swelling or draining wound beneath the eye that can break open and drain. The swelling can often be the size of a golf ball. When left alone, the opening can sometimes close and reopen as the pocket of infection reaccumulates.

Tooth root abscesses can occur in dogs of any age or sex. Most dogs improve in 48 to 72 hours with appropriate early treatment of the condition.

What to Watch For

• Signs of tooth root abscessation usually occur suddenly and include:

• Swelling of tissues below the eye or on the cheek

• Pain upon opening the mouth

• Not eating (due to pain) or reluctance to chew hard food

• Crying when chewing

• Lymph node enlargement

• Lethargy

• Fever

Diagnosis of Tooth Root Abscesses in Dogs

A thorough exam is performed including the evaluation of the face including the eyes, nose, and mouth. Attempts may be made to examine the mouth, but this may be too painful for your pet and may have to be performed under sedation. Often, a physical examination is all that is needed to diagnose tooth root abscessation. In some cases, additional diagnostics may be required and may include:

• Complete blood count

• Biochemical profile

• Urinalysis

• X-rays of the mouth and teeth

Treatment of Tooth Root Abscesses in Dogs

Treatment is aimed at eliminating the infection and treating the underlying dental problem. In mild cases, antibiotics and pain medications are usually started both orally, however definitive treatment includes a dental cleaning and care of the infected tooth which may include extraction or endodontic treatment (total pulpectomy and root canal filling). Endodontic treatment is generally treated in multiple appointments. Most dogs respond to treatment and improve in 48 to 72 hours.

If the signs are severe or worsen, dental cleaning and care may be treated as an emergency and performed within 24 to 72 hours following diagnosis. General anesthesia is needed for this procedure.

Common prescriptions may include:

• Carprofen is commonly given for relief of pain and inflammation. This is a non-steroidal anti-inflammatory medication. Do not administer this medication with steroids. This medication may have gastrointestinal side effects so please do not administer this medication if your dog is vomiting, having diarrhea, or refusing food.

• A variety of antibiotics may be prescribed. One commonly prescribed antibiotic for oral infections is Clindamycin which is generally given twice daily.

• Do not give human pain medications to animals at any time without the approval of your veterinarian.

Home Care and Prevention for Canine Tooth Root Abscess

If your dog is painful and has a draining wound from the face, a veterinary examination is recommended immediately. Once a dental abscess is diagnosed and treatment has been started, all medications must be continued at home exactly as prescribed. Such medications may include topical antibiotics or local wound care, oral antibiotics, and oral pain medications.

Your veterinarian may also ask you to apply warm, wet compresses to the wound three to four times per day for several days to reduce swelling and encourage drainage. Offer soft foods to help your pet eat until the swelling and pain have diminished.

To reduce the risk of tooth root abscessation discuss the best dental care plan for your dog with your veterinarian. Daily tooth brushing and periodic dental cleaning may be the best prevention strategy.
