Three of my 4 dogs love to chase the birds that come in to pick up fruit from the ground. All different breeds but all share that instinct. Fortunately the birds are smart enough to get away before the dogs get to them.
It’s so critical to make sure medium and larger dogs are secure in their yards unable to do this kind of damage.
I was talking with a lady the other day who moved in with this guy who has 40 acres out in the desert. They have 4 dogs between them. One day they took off like they do (it’s a country dog thing) and when they came back one of them was carrying a burro leg to chew on. I don’t know if they pack killed the burro or found it out there killed by something else. She came into that relationship with a puppy; now it’s grown up and part of that pack it’s there for life. Those dogs would never tolerate a 1/4 acre fenced yard. They are country dogs now.
All the lots are acreage out here-the one I live on is small-3 acres-I’ll find a bigger one because I want some goats. Even living on fenced acreage, I never, ever left my Husky unattended/alone outdoors and never went hiking in the woods without her wearing her harness and on her leash-Huskies and other close-to-wolf large dogs just have too strong a prey/hunting instinct for them to be loose or unattended. I’ve never had a small dog-and only one dog of mine was not on the “bad dog” list-an Aussie shepherd-might as well have been because she wanted to herd everything-with unnecessary roughness that would’ve caused death to a smaller creature. And since I live in the middle of nowhere I prefer the large guarding/working breed dogs-I always chose a female from a recommended kennel when I buy a puppy-I want a dog that is loyal and protective.
