Before we got Maggie we had Mitzi, a grumpy old lady who attacked all other dogs she met. I was more than concerned how it might go between the two of them. Surprisingly Mitzi was really nice to Maggie after the boundaries were set. I think if you let the two meet outside your house for the first time there is going to be less stress on your boy.
BTW... if he barks and attacks other dogs it means he is insecure and some treats as often as you meet another dog does wonders... |
