Skin Scrapes: More than just scratching the surface
 

You may have heard the term “skin scrape” when the veterinarian suspects a parasite is living on your pet. You might wonder exactly what the doctor is doing. Literally, he or she is using the blade of a scalpel and gently scraping the skin, usually until a small amount of blood is seen. The doctor is gathering skin surface debris, skin cells, and the contents of hair follicles that lie deep in the skin.

The collected sample is then placed on a microscope slide, mixed with mineral oil and examined under a microscope.
(Pictures show scraping a location on the muzzle and the sample on the scalpel before placing it on a slide.)

The primary focus is the positive determination of a mite. Demodex canis and Sarcoptes are the two most common mites that can cause pets’ severe skin irritation and hair loss. These parasites cannot be seen with the naked eye. A flea, although small is still about 8 times larger than a mite. And fleas will live on the skin whereas the mite will burrow into the skin or hair follicles. Therefore the scrape is going below the skin surface to find the parasite.
A skin scrape does not require the pet to be sedated and only mild and temporary discomfort is the result.
The doctor can usually determine if a parasite is present during the office visit. Although some mites such as Sarcoptes mites can be very difficult to find and a negative skin scraping does not completely rule out their presence. Therapy is based on the type of mite present and/or suspected but can usually be resolved readily in most cases.

National Bite Prevention Week:
May 21-26
 

     May 21-26 was National Dog Bite Prevention Week and although that date has passed, it’s not too late to learn to understand the signs of fear and anxiety in your dog that can help avoid a dog bite.
     According to veterinarian and animal behaviorist Dr. Sophia Yin, the common practice of approaching a strange dog and offering your hand as a friendly gesture isn’t the safest way. The belief is that if the dog has the opportunity to smell your hand, the dog’s fears will be allayed and it will then be safe to touch the dog. Not so, says Dr. Yin. Dogs, like people, have a “personal space” and it is better for the dog to approach a person when the dog has reached its comfort level.
     Dr. Yin has identified some of the body language of fear in dogs and placed them in an informative downloadable poster on her website at www.drsophiayin.com.
The associated article offers tips and suggestions when working with a fearful dog.
“For the human who is approaching, the first rule is to ask the owner first, and then ask the dog. That means, turn slightly sideways so you’re not facing the dog squarely or staring at him. Then let him approach at his own rate. If he shows any combination of signs of fear or anxiety, avoid reaching out to pet him.”
