Last Friday night I noticed my dog Fenway had blood in his soft stools. I had to work on Saturday and left for North Carolina on Sunday. I left him with my sister and told her to watch him and that if he doesn't seem right, to bring him to the vet. I called her several times while I was in NC (I'm from NH) and she said he wasn't eating and that she thought he just missed me. I told her to call the vet and she did (making an appointment for when I got back to NH-on Wednesday). In the meantime, I was worried sick about him. I insisted she take him to the emergency vet but she insisted he just missed me. Well I went to pick him up on Tuesday night when I got home and I could tell he was sick. His fur looked unhealthy, he had stuff coming out of his eyes and he had blood coming out of his mouth. My sister said she didn't notice the blood and the eye situation just happend that day. Anyhow, I drove 95 mph to the emergency vet and told them about the blood in his soft stools and the blood in his mouth and the stuff coming out of his eyes (crusty/watery stuff). They smelled his mouth and they said it smelled rotten, like he had an abcess. They gave him general anesteshia (spelling?) and looked in his mouth. Sure enough, he had a abscess. They drained it and he is now on antibiotics and feeling about 75-80% better. They said the abscess bled and he would swallow the blood and it would come out in his poop. That would also explain why he wasn't eating - because it hurt too much. I've forgiven my sister, but I don't think I'll ever have her babysit my dog again (and she has TWO Labs and FOUR cats!) You'd think she would have broughten my dog to the emergency vets! Anyways, I would call your vet asap. Perhaps your dog has an infection that can easily be treated with an antibiotic. Good luck! I'm sure your dog will be fine.
