Brown fur from licking.

Dr. Marie replied:

Hi Julie and thanks for your question.

By far the most common reason for a dog to lick in those areas is allergies. However, food allergies are actually not that common. Most often when a dog has allergies it is because they are allergic to something in the environment such as a weed like ragweed. Usually we can't find the source of allergies.

The fur is stained brown because that is what happens when saliva repeatedly touches the fur. It will eventually go away once the allergies clear up. You can also buy good products in the pet store or at your vet that will help you to clean these areas.

Regarding the allergies, in many areas allergy season is coming to an end and you may find that your dog clears up on his own. If you live in an area that is cold enough to see frost then once there are a few good frosts most dogs start to get better.

But, many dogs do need prescription medications to help with the itching. The most effective medicines are steroids such as prednisone. When we give prednisone to a dog for allergies we give it in very small doses and it is not harmful to a dog.

While there are a few dogs that do ok with antihistamines the vast majority do need some steroids.

Regarding the food, if your dog has an environmental allergy then changing the diet will not help at all.

I hope this helps! If you think he needs medication your vet will likely want to take a look at him just to confirm that this is indeed allergies.

Hope Plato is feeling better soon!

Dr. Marie.
