We have 4 month old staffy/kelpie puppies, and one of them appears to be quite vicious. Fred is constantly trying to boss Ginger, and he has attacked her a couple of times, in almost a frenzied attack. It's like watching a dog go crazy at dog fights.
We have a dog yard with a kennel we put them in at night, and she got out, and when we put her back in, he attacked her. Reared up, trying to get at her throat, savage attack.
I am worried that as he gets older, he is going to be more and more vicious. He hasn't acted this way towards us humans yet (just spends a ridiculous amount of time barking at the cats). Ginger is more boisterous with us..she jumps on DD when she is excited.
Will he calm down? I don't know what to expect.
