Give him some time. He'll be wiser now. He'll know not to jump on critters that are as big as he is. I have a 25 pound miniature Husky named Sue (named her after my late mother-in-law, who was a fine lady) that rules my back yard. Sue has killed at least 3 Opossum's, 2 squirrels, 2 rats and countless moles and mice. My Sue has the same black&white markings as your dog, except Sue has brown eyes, she's 3&1/2 years old.
I had 2 Female full size Huskies about 15 years ago, they killed everything that came into the yard, same as above except they killed house cats also. They were "Cinnamon" huskies, one was Honey backed with a white bottom and the other was brown and white. I called them my "fighting bitches" because the fought at least once a week. The yellow backed blue eyed dog never understood the the brown backed amber eyed dog was "boss'.
