What Does a Skin Scraping Reveal in Dogs?

As you might know from our article on 5 common dog skin diseases, skin problems and constant scratching from itchiness are common disorders found in dogs and other animals. Finding the reason for the problem is important in order to appropriately approaching an effective treatment or cure.

What’s a skin scraping test?

A skin scraping is a collected sample of skin cells that are evaluated under a microscope. Skin scraping tests are typically performed to aid in diagnosing certain skin inflammations, fungal infections, and skin cancer, along with being an effective way of determining the presence of mites.

What does a skin scraping reveal in dogs?

A skin scraping can reveal the presence of abnormal cells in the superficial layers of the skin. It can reveal certain fungi, bacteria, cancer cells, and parasites. Determining the underlying cause of a skin disorder leads to appropriate treatment.

How are skin scrapings done?

With the use of a scalpel blade, a sample of skin cells are collected. The blade is used to gently scrape layers of the skin, usually until a small amount of blood is seen so that cells that are deep in the skin are gathered. This is important because parasites often live deep in the skin. Once the skin cell sample is collected, it is placed on a microscope slide, mixed with oil, and evaluated under a microscope. Results are typically available within 30 minutes, unless a veterinarian may need a second opinion and it is submitted to an outside lab.

Are skin scrapings painful to dogs?

The level of pain varies from one dog to another and is more likely to cause discomfort rather than pain. Neither sedation nor anesthesia is needed in order to perform a skin scraping. Most dogs tolerate this procedure relatively well.

Feline Skin Diseases: When is licking more than just grooming?

Dermatopathies (skin diseases) are quite common in cats. Studies indicate that between 6% and 15% of feline patients have at least one dermatopathy and many cats suffer from more than one. A recent study done by Cornell University Hospital for Animals showed that 22% had two skin diseases and 6% have three distinctive skin diseases.

The skin is the largest organ in a cat’s body, which comprises up to a quarter of its body weight. It also has many important functions, such as a protective barrier to the environment and regulates body temperature.

The skin of a cat is composed of:

The epidermis

The epidermis is the top layer that provides protection.

The dermis

The dermis is the supportive layer underneath the epidermis, which provides nourishment to the top layer.

The subcutis

The subcutis is the innermost layer that contains protective and insulating muscles and fat.

The appendages

The appendages include the claws, sebaceous glands that lubricate the skin and hair, and tiny muscles called arrector pili that can make hair stand on end.

Leading causes

Numerous conditions, from parasites to allergies, can cause skin diseases in cats. The geographic location is also linked to the prevalence of certain conditions. In upstate New York, for example, the most common causes of skin disease in cats seen by dermatology specialists are allergies to airborne particles, food, or flea and mosquito bites. On the other hand, in other countries like Canada and the United Kingdom, studies show that abscesses are the most common cause of skin disease in feline patients.

A cat’s lifestyle, gender, or breed can also affect their risk of various skin conditions. Outdoor cats for example, have a greater chance of infestation by external parasites (such as fleas) and a higher risk of injury and abscesses from fighting with other cats or animals. Additionally, male cats are more likely than female cats to engage in aggressive behavior that may result in bite wound-induced abscesses. There are also certain breeds, like Himalayans, which are more prone to skin disease than other cat breeds.

Common (clinical) signs of skin disease in cats include:

• Excessive scratching, licking, or chewing of the fur

• Loss of fur

• Scabby, scaly, or flaky skin,

• Swellings or bumps on the skin

Treatment of skin disease in cats

The treatment of feline skin disease depends on its specific cause. Flea infestation is treated by using certain flea control products to eliminate fleas from both the cat and its environment. Food allergies are typically treated by a set diet that does not contain ingredients in which the cat is allergic to. Abscesses are treated by draining the infected site and putting the cat on antibiotics to fight any bacterial infections. Fungal disease is treated with anti-fungal medications. Often in cases, the cause of skin disease in cats may transfer to other cats (and in some cases, to people), so preventing transmission from animal or human is often an important element in a treatment plan.

Cats with a skin disease will often suffer from dermatitis (skin inflammation). The inflammation may result from the process that starts the disease (like food allergies or the cat itching and scratching in response to the irritation stemming from the disease). In both cases, inflammation leads to itchiness, and thus scratching expedites skin damage (triggering a possible, yet relentless cycle of inflammation and skin damage). Careful consultation with your vet can help you arrive at the best strategy to treat your cat’s skin disease.

Prognosis of skin disease in cats

Depending on severity or cause of feline skin disease, the predicted outcome for cats is often favorable. There are rare exceptions where skin disease in cats is an indicator of a more serious illness, however by visiting your vet and following the treatment plan closely with your feline, the result will lead to resolution of the problem.

Bladder Stones in Dogs

Some of the most dramatic X-rays shown to clients are those that reveal the presence of large stones in their dog’s bladder. Until they see the X-rays, many of these folks are a little annoyed at their dog. This isn’t unreasonable, considering the dog often has accidents in the house or needs to go outside on an hourly basis. However, after seeing the X-rays, most owners are shocked that their dog hasn’t been acting even sicker.

What are the Signs of Bladder Stones in Dogs?

Bladder stones start out small but over time can grow in number and/or size. Dogs with bladder stones typically have some or all of the following symptoms:

• Urinary accidents

• Frequent attempts to urinate without producing much urine

• Straining to urinate

• Discolored urine

• Licking around the urinary opening

These clinical signs can be seen with other diseases affecting the urinary tract (infections or tumors, for example), so the diagnosis of bladder stones has to be confirmed with either an X-ray or ultrasound.

How are Bladder Stones Formed and Treated?

Bladder stones are a collection of minerals and other materials. Most bladder stones in dogs are made from struvite, calcium oxalate, urate, or cystine crystals. In many cases, the specific type of crystal involved can be seen in a sample of urine viewed under the microscope.

If struvite is the diagnosis, a veterinarian will treat the underlying cause (e.g., antibiotics for urinary tract infections) and may recommend a therapeutic diet that will dissolve the stones and crystals. Dogs prescribed antibiotics will typically use the drugs while consuming the therapeutic dog food, and possibly longer if needed. Surgery or other procedures like lithotripsy (breaking up the stones with ultrasonic shock waves) will be necessary to get the stones out of the bladder. The therapeutic diet for dissolving struvite stones, however, must be given under a veterinarian’s supervision. This is because they are formulated to make the dog produce more acidic urine than they would otherwise in order to break down the stone. If urinary acidification is taken too far, calcium oxalate stones can be the result.

 
What’s the Best Way to Prevent Bladder Stones in Dogs?

Once the stones are gone, diet plays an important role in preventing their return. Manufacturers have formulated special foods that deter the formation of struvite, calcium oxalate, urate, and cystine crystals. Encouraging water intake is also important since crystals are less likely to form in diluted urine. For this reason, many veterinarians recommend the canned versions of these foods over the dry.

Because diets designed to prevent bladder stones have to be fed over the long term, they must be nutritionally balanced. Your pet’s doctor is in the best position to recommend a nutritionally complete, well-balanced food that will help keep your pet healthy.
