Hi, I have 2 dogs, a 13yr old Sheprador and a 7yr old Staffordshire bull terrier. They both have great temperaments generally speaking. Today I brought home my new puppy after waiting 6 weeks for him to be ready! My Sheprador is fine with him and just lets him get on with things, however my Staffy is a little hostile. Initially he sniffed his back end and then his face, walked away and left him to it. Now his hackles go up and he runs away in order to avoid him and growls if he doesn’t want to move but the puppy has come up to see him. I have followed Cesar Millan’s method of training with my Staffy but it is so hard to find general advice anywhere. My question is how do I deal with this? Do I make my Staffy stay in the same room as the puppy, or do I let him have his own space and get used to the puppy in his own time? All of my animals have always got on but the Staff was my latest addition until today (I had the Staffy from 8 weeks old too). Thanks!
