Amber: I would suggest you give your vet a call, especially since the diarrhea started again. You wouldn't want to risk the chance of something more serious than a cold (if that is, indeed, what Amber has on top of the colitis). Re fever: you can take your beagle's temp with a children's rectal thermometer but it does take two humans to do this -- one to firmly, but gently, hold the pup and the other to insert the thermometer. As I recall, a dog's normal temp is between 101 and 102. (You can't go by a dry nose -- my Maggie almost always had a dry nose.)
