HELP ME! Something is wrong with my dog! What could it be?

I do not like to criticize a vet that I do not know but...I feel for you and would rather not see you go through another loss. I know all too well what it feels like and I know what it feels like when you know something is wrong and the vet will not listen. You know your dog better than anyone and you know in your heart something is wrong. Take the dog to another vet. Do not call. Just go in. You may have to wait, but if it is an allergy, there are shots that can be given to stop it. However, I have seen some diseases that have the symptoms you have described. If you can, get a sample of the dog poo (I know it is gross) to take to the vet and this will help him see what is going on better. I cannot see your dog so I do not want to guess at what is going on, but I have seen similar symptoms before. I hear you. Take your dog to a vet that will hear you too. Good luck and let us know what happens. Please post a message on here when you find what is wrong as I would like to know since I recently had a similar incident.
