My dog is loosing a lot of her hair recently, she has bald patches on her neck and back. The one on her back is in an area that usually has very thick fur but you can see right through it now. The patch on her neck is getting bigger and is larger now than in the photo attached. What does this mean?

There are many reasons for a dog to lose hair and have bald patches. Common ones are: * low thyroid level * Cushing's disease * flea allergy * other allergy * auto immune disorder * bacterial or fungal infection I strongly recommend you have Annie Mae examined by your vet to try and get to the bottom of what is causing her symptoms. We cannot diagnose over the internet.
