Hi. I have a 5 year old female boxer at home. She started loosing her fur on her back around a month ago. Happened last year with no problems. Its happened this year with no problems at first. Two weeks ago she stopped eating her food and wouldn't drink. We started syringing water into her mouth and trying to force food into her. Didn't work. We are just over two weeks from that day and she's lost over 10% of her body weight. She wont eat and when she does she throws it back up in either bile or pure water. She still gets excited over the word walk but not as much as she used too. She isn't herself and seems all depressed. We are really worried because shes lost so much weight her skins all saggy and she's a bag of bones. Has anyone experienced anything like this before? We are petrified to take her to the vets incase its a sad ending. Just after a few bits of advice. Thank you.
