HiCustomer

 

If there is hair loss involved, it could be a few different things. Since I don't know what your vet has ruled out, I'm going to give you all the options. Unfortunately, there are many conditions that can cause a dog to experience hair loss including ringworm, mange, hypothyroidism, cushing disease and allergies.

 

Ringworm can have a scaly reddish rash around the edges of the bare patches though there can be a rash in the bare area as well. Any over the counter antifungal cream for ringworm will work on this. The cream should be applied to an area slightly larger and for about a week after it appears to have cleared up. There are two types of mange and mange is actually caused by mites. Usually hair loss starts in specific areas of the body before spreading to other areas. Allergies are a frequent cause of scratching and hair loss and an be caused by many different things. Treating any problem without knowing for sure what it is causes a delay in the treatment of the real problem if your first guess is wrong. I really suggest you have your Vet examine the areas and diagnose this. Below are websites that will go into more detail on these conditions.

 

Here is a website on Ringworm:

Here is two on Mange.

Hypothyroidism and cushing on these pages:
http://www.petplace.com/dogs/hypothyroidism-in-dogs/page1.aspx

You can read up on allergies here:

http://www.lbah.com/allergy.htm

 

If you suspect an allergy condition is to blame, you can give your dog Benadryl up to 2mg per pound every 8 hours which I see you are already doing so I suspect your vet mentioned allergies as the cause.

 

There might be a secondary skin condition in addition to the allergy such as staph dermatitis or yeast dermatitis. Staph usually occurs on the lower regions of your pet and tends to have small pimple type bumps. Shampoo containing Chlorhexiderm and/or Oatmeal can help with this condition though it does not cure the allergy. Yeast typically shows as a greasy area that has a sweet musty odor. Sometimes the skin can become inflamed, darker and thickened due to itching. Yeast likes areas such as between toes, armpits and ears. Selsun Blue Shampoo can help with Yeast dermatitis. When shampooing, lather and leave on 15 minutes before rinsing. These shampoos are not meant to be a cure, just a relief until your pet can see a Vet.

 

There is also a condition called alopecia which is basically hair loss. You can read all about it in this article:
http://www.dvmnewsmagazine.com/dvm/article/articleDetail.jsp?id=7250

 

Some treatment methods for this are discussed on the following site. You might want to discuss this possibility with your vet.
http://www.vin.com/proceedings/Proceedings.plx?CID=WSAVA2004&PID=8629&O=Generic

 

Unfortunately, in cases like this, your vet treats the skin dermatitis with steroids (predinsone), antibiotics, sometimes shampoos, but never addresses the underlying allergy which causes the skin issues. Food trials can be done, and this is effective when a food switch triggered the skin issues to begin with. I see you have switched foods as well, but if the new food contains similar ingredients, it wouldn't eliminate the allergen. I personally think that allergy testing, while expensive, is cost effective since then the allergen can be avoided or the dog desensitized to the allergen.

 

If there is no hair loss, then a skin infection such as yeast or staph is still possible and dry skin might also be an issue. You can give Fish Oil capsules to supplement the dogs diet iwth Omega n3 fatty acids which do help with dry skin and coat issues.

 

I hope this information is helpful.
