Thanks for your reply..My dog stopped vomiting, but he is having loose stools. Now I started force feeding him by using a syringe. And now he is improving. But he hasn't started to eat on his own. But he is not vomiting if we force feed him. What kind of problem this could be?
I am sorry about your dog. Vomiting can be caused by a great number or problems including: parasites, gastritis, toxins, infectious agents, foreign body ingestion, kidney or liver disease, cancers and more. Not eating for two weeks is very serious.
It would be great if your vet's were able to perform blood tests and X-Rays because once there is a diagnosis proper treatment can be instituted. If diagnostics cannot be performed than symptomatic treatment is the next best option.
Symptomatic treatment for a vomiting, anorexic dog include:
1. anti-emetics (anti-nausea medication) such as Reglan, Cerenia, or equivalent;
2. appetite stimulants, such as Mirtazapine (Remeron), Cyproheptadine (Periactin), or equivalent;
3. steroids either given orally or by injection and IV fluid therapy;
4. antiparasitics and antibiotics should also be given, including Metronidazole or others.
If your dog does not improve he may sadly have something very difficult or impossible to cure such as cancer. I sincerely hope that he does have something curable. Good luck!
