The day I posted the previous article about our dog, I learned that he has Giardia. This would explain a lot of his problems. He was put on two different types of meds to get rid of the parasite and he was doing fairly well until this weekend. Some minor, yet consistent vomiting started up. Gave him some Ace and other pills and that was able to get him through the night without vomiting. This morning he seems to be doing better, but I think that is still up in the air a bit. Will continue to post articles about once a week as updates to his health.
