I have two dogs, one of which is a 10 month old puppy. He's a Bernedoodle and about 80 pounds (so far) and while rambunctious and excitable, as gentle a dog as you can imagine. He hasn't chewed up a single piece of furniture or a single shoe left on the floor, but he does a pretty good job chewing up his toys. Where I live we have more than occasionally spotted a coyote, some of which are pretty large. But I doubt that a coyote would attempt to attack a dog of 80 pounds being walked by a human, but I am not sure about that by any means. What I wondered about was how my big and clearly capable puppy would react if actually attacked by a deadly coyote? Would he just yelp and try to get away, or would the wolf genes still in him get him to fight back against a predator? I carry pepper spray and a pocket knife when we go for walks, but leave my handgun behind because we walk on the grounds of the local community college where of course carrying a gun is illegal. So it has crossed my mind that despite his size he might well be no match for a hungry coyote.
