Introducingan alpha type puppy to non alpha neutered male adult
I have a8 week old german shepard pup and am introducing her to a household with a 6yr old whetland terrier (popeye) who has always been the submissive dog with our other dogs - the last alpha passed several months ago. Popeye at first just stayed on my bed and would show his teeth and growl when the puppy did more than just walk by but would interact a tiny bit in the backyard. Now he comes out to the living room and the puppy is getting more aggressive... barking and laying down then barking standing up.. she is trying everything to engage pops but nothing is working. Popeye also lets her eat out of his dish and lay on his bed. We pay tons of attention to pops but still very little interaction and no playing. Pops appears to not want to stand up and be alpha but not to be a playmate either. We got this pup because we all missed having a second dog... including pops, or so we thought.
Need some help with getting these two to interact/play. Pup is crated at night which gives pops a chgance to get his 1 on 1 with his people, but I think if he would break down and play they would have a great time... please help mary
