We just (as in two days ago) added a third hound to our house. The second and new one get along great, but the first one has become a bully. We are using muzzles, walks, and no unsupervised time but how can we ease our first one’s stress and help acceptance of the third? I know it’s only been two days, but I want to ensure we are doing everything the best way. In case it matters hound 1—girl, never raced, brought home at 15 months, is now 3 and has also been an alpha. 67 lbs. Hound 2—-girl, raced for a brief time, brought home at 2.5 years, is now 3, and is very submissive 64 lbs. Hound 3—boy and littermate to hound 2. Raced for a longer time, is 3, seems submissive, 80lbs.
Any input is appreciated.
