OK well the dog I'm sitting is still throwing up. I came over after school on Wednesday and she had Thrown up twice and had diarrhea twice. I figured she may be missing the family so was stressed out. She was acting fine, super playful and energetic. She was fine when I took her out that night, solid poop. Same with Thursday, she was fine all day. Then Yesterday I took her out in the morning, she peed but no poop and when I came over at 3 (after school) there was 1 big pile of throw up, two piles of diarrhea and a big mess of pee. The throw up is always bile, no blood in anything. When I take her out she is continuing to have diarrhea. This morning I went over and she had thrown up a small amount, it was pinkish but I really don't think it was blood once I wiped it up it did not have the pinkish tint (and the floor is pink so it could have affected it). Now she is not as peppy as usual so I'm getting really worried. Do you think I should bring her to the vet? The family will be home Sunday late morning. Do you think I should call them and ask if they want me to bring her to the vet, I have their number and the vet's number.
