Dog ate chocolate?

Bald patches on body.

Species: Dog
Breed: labrador retriever
Age: 2-5 years
I live in Spain. Last Spring my dog had hard white lumps of skin down the sides of her body which came off and the fur came away with it. It left new skin with no fur. These patches were not sore and she did not scratch so were not itchy. Now its December and it has come back again.

The vet tested skin and there was no infestation and blood test was normal.

Do you have any suggestions for treatment and do you know what this is.

Dr. Marie replied:

This is a tough question to answer without being able to see Freya.

It is interesting that she was not itchy. I'm wondering if what you are seeing is something called a seasonal flank alopecia.

Here are some pictures of dogs with seasonal flank alopecia:

cyclical flank alopecia

This is really common in boxers but can happen in other breeds as well. I have seen it in Bulldogs, Labs and Golden Retrievers.

If this is flank alopecia we really don't know what causes it. Some people will treat it with melatonin but usually it goes away on its own within a few weeks.

The way to diagnose this would be to have your vet take a skin biopsy.

I hope this helps!

Dr. Marie.
