I am beginning our search for our next family dog. We have a toddler and the mastiff breed appears to be what we are looking for. I've read up on the breed, but wanted actual owner and breeder input to see if this is in fact compatible with our family. This will be our first large breed dog. We've mostly owned medium size, border cookies mixed breeds, etc. We are a laid back family that lives on several acres. We are looking for indoor. My main questions are temperment for a first time large breed owner, chidren and other pets, any special care required, etc. The bullmastiff and the English mastiff are both on our research list. Thank you any responses provided! I would love as much info as possible.
