I have a 2 year old, 5 pound, Chihuahua who stopped eating completely about a week ago. About 2 days before he stopped eating he got into a box of dog dental chews, he only at 2 of them and the next day threw up about 6 times and have diarrhea. This only last about half a day and his poop has been solid since, although he has not pooped in about 3 days now since he has not eaten anything. In the first couple days I got him to eat VERY small portions of food which he threw up about 4 hours after eating. Three days ago he ate a small dog treat and kept it down! We have been to the vet 4 times now and spent over $1000 and they still know nothing. Blood work showed his liver enzymes were slightly elevated but everything else was fine, x-rays showed there is a possibility of entinitis in his small intestines. He is on antibiotics for this but the vet said this would not result in him not eating. There have not been any changes in our life or daily routine that would effect his eating habits and he has never been a picky eater; he eats everything he can. This being said, other than the couple dental chews, there is nothing we can think of that he could have gotten into. The vet has given him anti-nausea medicine and an appetite stimulant, neither even spiked an interest in food. He stayed at the vet for 2 fully days on an IV to keep him from getting dehydrated and since then he has been drinking water but still not eating. He just seems so miserable and I am so worried there is something seriously wrong with him. I am thinking about going to see another vet, I just want him to feel better but I don't have the money to spend another $1000. Any suggestions or ideas you have, please let me know! Thank you!
