They’re both awesome breeds I prefer the BMD more but for god sake‘s don’t buy a tiny little dog, get a real dog anything less than 50 pounds as an accessory not a dog. Lol.
I have a berner and a 26 pound dog.We call them the bark and the bite. They make a great team. One is the watch dog( the Cavalier) and the berner is the guard dog. Love my dogs !!!
