Hi there this is a non bulldog question but my mom is getting two bullmastiff puppies on monday and we were wondering about crate training. right now they are used to being with there brothers and sisters in a large play pin, but she is wanting to potentally crate train them. Should she get two crates? one larger crate they could both fit in? If she does get two crates, place them side by side?gosh, how do you go about trainging two puppies at once?
