I just left my dog a the vet’s office for the weekend. He wasn’t feeling himself last night (which I thought had more to do with the 100 degree temps) and this morning around 10:00 he started throwing up, then almost immediately the diarrhea started. I kept an eye on him and checked his poop and vomit for signs of what might have made him sick (the things we do, huh?) and noticed blood…to me a significant amount. He would assume the position and he just dripped blood instead of poop. He was drinking water normally. He is a 42 pound 6 or 7 year old mutt and otherwise seemingly healthy. http://i833.photobucket.com/albums/zz258/dorim_2005/dogs/IMG_5056.jpg He is on comfortis and heartguard (last given last weekend). He ate his dinner last night (blue buffalo) and appeared to have a normal BM but just seemed a little depressed after dinner. The vet didn’t seem too concerned…was going to give him a shot of something for the nausea and keep him for observation. He didn’t think that he needed a bunch of expensive tests…yet
I realize it could be anything…but any ideas?
