hi everyone, I need some help. I have an 11 year old cocker mutt and she is very sick. About 2 1/2 weeks ago she started not being able to jump up on the bed or put a lot of weight on her right hind leg. She would never whine, like it wasn't hurting her at all though. About a week ago she started vomitting bright yellow stuff, that's when I realized she hadn't really eaten lately. She only vomitted for a couple of days but now she still will not eat. It's been six days and all she's had is a dozen treats. I took her to the vet on Tuesday, was given pain meds to see if it was her leg. I was told that if she didn't get better to call the vet back on Thursday. She didn't get better and I took her back yesterday. The vet did x-rays and found nothing and said if she doesn't eat by Monday it's time to put her down. Now she's always been a healthy dog, if fact about six months ago during a regular vet check up the vet thought she was only about 6 years old because she is so energetic and healthy. She is still that way told, even though I know she's sick. I just feel that it's not her time to go but I also don't want her to starve to death. Any ideas to what's wrong?
