I am assuming that this is a dog? The areas of hair loss on the skin could be caused my a multitude of problems, but most common would be something called demodex. Demodex is a mite that is present mostly in very young dogs or dogs with immune suppression from other conditions. I would encourage you to have her evaluated by your veterinarian soon. They may recommend a skin scrape to look for mites. Sometimes even if they aren’t found a trial therapy is still recommended. Best of luck and I hope they resolve quickly.

    This can be a few different things. MItes, allergies or even fleas. I would say less likely fleas due to the location of the hairloss. It can be allergies or probably a type of mite. There are two different mites that it can commonly be. One is called Demodex and this is a normal mite in the hair follicle but does tend to over grow in puppies, causing hairloss. This is easily treated and found. Your veterinarian can perform a skin scraping to determine if this is what Cookie has. The other mite is hard to find and causes intense itching. It also can easily be treated and if she is negative for Demodex or has the symptoms of Scabies sometimes we just treat for Scabies to be sure. I would recommend bringing Cookie to the vet to have them look at her skin and perform a skin scraping. If they feel it is more allergy related, there are great options with allergy medication in dogs now and your vet can discuss the options you have for Cookie.

    A common mite called demodex will often cause hair loss without itching. Also, Skin infection caused by bacteria or a fungal infection such as ring worm is also possible. She is a little young for hypothyroidism, but it is still possible. I would highly encourage you to have her evaluated by your veterinarian soon. They may do a skin scraping to look for mites and may recommend blood work to check her thyroid level. Best of luck and thank you for using Pet Coach.
