That might be best, as I can't diagnose this. I don't know what might be wrong. I hope your dog will be OK.
Well, the drinking water might be making her sick and plus the anxiety of not having you around. Losing hair could be some sort of mange maybe too.
I would find out what the doctor thought after her exam and what kind of shots he gave her.
Good luck.
Thank's for trying to help but I founf out what my dog has it's called Sarna and I'm not sure what's going to happen to her yet but I'm hoping for the best.
I believe "Sarna" is Spanish for Scabies, a skin condition caused by a very very small mite which burrows into the skin. In dogs it is also called "Sarcptic Mange".There are very effective treatments for this.
Once I had a dog who got this. The vet said he had picked it up in the fields, from wild foxes (there are a lot in my area) He gave my dog a shot, then some special shampoo and ointment. It all cured it.
Unfortunately this condition can pass from dog to human. In humans it is known as Scabies. The people who live with your dog will probably also need scabies treatment.
....sorry a typo there....I meant to write "Sarcoptic Mange"
