Hello, our 12 week old puppy has had diarrhea for the past three days. We think it started from him eating the some of our other two adult dog's food. We bought some anti-diarrhea liquid which has kaolin and pectin and his stool turned alot more solid and partly white, which is the color of the liquid. We gave him boiled chicken with rice last night and he ate it no problem, but threw it up about 1 1/2 hour later. This morning his diarrhea was back with light blood in it, and he has no appetite. He doesnt't want to eat the chicken and rice. He has been drinking some water and his nose is moist- it was dry last night. Any suggestions before taking him to the vet?
