I have a 5 year old Border Collie cross Labrador. She has always had perfect health up until 2 years ago when she had a period where she wasn't interested in ANY food and would vomit bile. She was admitted to the vets who run blood tests etc. These all came back clear. She was sent home with a jar of Antepsin to have 5ml 3 times a day. She seemed to get over it and was back to normal in a few weeks.. Up until 3 weeks ago.
She has started to be off her food again and has vomited bile with blood in a few times. She has also passed a couple of very dark stools, also spotted with blood.
We took her to the vets who admitted her over night again. She came back to us the next day, with the vet saying everything seemed fine. She was given another bottle of Antepsin. She is hydrated, a healthy weight, perfectly fine in character, still loves to go for walks etc.
She just doesn't want to eat anything, we have offered her normal dog food, vegetables, egg, rice, chicken but she just doesn't seem interested. She hasn't eaten her full day's worth of food in around 3 weeks now.
The purpose of this post is to ask if anybody has any opinions on the matter as I am becoming increasingly worrid about her and I am beginning to wonder if there may be something more sinister that is being over looked.
