I feel terrible! About 4 days ago my dog ate a dirty diaper that I had forgotten to throw away right after my baby's bath. He took it off the counter before I realized my mistake. He was fine until yesterday, and has been having bad diarrhea and gas. He threw up once too. He is eating and drinking normally, but I was wondering, can dogs get an intestinal infection from something like this? I called my vet but he hasn't called back yet and I am worried!
