... pretty easy to train and good with people. They are high energy and tend to not have lots of chronic health problems. I'd take the dog to the vet if the diarrhea persists, but it might just be adjusting to new food.

I strongly recommend crate training the dog (you can google how, it's a common method). We've crate trained all but one of our dogs and that one was the most prone to "accidents" as an adult dog. We generally crate trained the dog until it was a year old and then would have very few problems after.
