Two weeks ago our 4 dogs developed explosive diarrhea. We make their food and have for the past 6 years. We couldn’t figure out what caused this, we checked the yard for pooled bad water, animal carcasses, etc. The diarrhea cleared up after a couple days after we changed their diet to chicken and rice. We realized after seeing the Jif issue last week, that we gave the pups their heart worm pills mixed with a big dollop of peanut butter. Turns out the lot number for the peanut butter was one of the bad ones. Have to think that with all the dogs developing the same symptoms at the same time, it had to be the peanut butter since we have never had this issue in the past.
Instead of peanut butter, try the little Vienna sausages that you buy in the small cans. That is what we use to give our dogs any pills. They love those things.
