I have a 8yr old pitbull who has been suffering from diarrhea, gas and extreme weightloss for over 5 months now. She eats and drinks regularly with no other symptoms. Ive taken her to the vet and have had her stool tested, a urinalysis done and a full panel blood test and over $600 spent. Her results from our vet says she is healthy and nothing came up on any of her tests with money so tight that was really tough to hear that shes healthy when i know she isnt…. I’ve switched her food over to grain free and also tried probiotics and digestive enzymes but still no results and she continues to waste away. Im broken hearted and dont know what the best thing to do for her now. Shes depressed and sad and has been having accidents lately which isnt her. Any advice or anyone else with this problem? Shes an angel and such a good dog im open to any suggestions/advice.
