These two are too large to be Samoyeds and the teeth are definitely wolfish. A former neighbor had a timberwolf as a pet and he had the same teeth. Beautiful animal and he behaved exactly like a dog. His one unfortunate habit was to howl unpredictably.
My friend has a crossbreed between a german sheppard/border collie and a.... something. The owner saw a coyote "in position" and assumed the pups would be, since that was the only "dog" in the area, but some of the puppies got much bigger than any coyote.
Friend kept seeing one of the at the time grown puppies laying on her porch waiting for her daughters to come home from school (at which point he would chase their tennis balls until the girls went inside for whatever reason.) For Xmas (with Friend's say so) the neighbor gave the dog to Friend's daughters.
It looks like a large coyote. It does not look even slightly like a dog. If you saw him you would say "Holy Carp in a pond! Coyote!" (which is why he has a lovely and very thick neon orange harness) The only time he looks like a dog?
When he herds friend's chickens/goats/cows/kids towards the nearest appropriate area. Also he can herd drunks. But he tries to herd them into the garage for whatever reason. He is a very good sheepdog, which is funnier if you know that no member of Friend's family actually knows how to train a sheepdog, nor does the neighbor who gave the animal to them. But if you whistle he will herd the nearest group of available animals towards you, or if its a drunk, towards the garage.
Oh, and if you scream at "his" girls or make them cry he will take you down. He has never drawn blood, but he snarls and growls in a manner that leaves no doubt that you need to stay the [blank] away from "his" girls. (He's done this twice. Once to a diffrent neighbor who was cussing at the girls about someting between him and their parents, and one to a drunk uncle who was trying to pull off the older girl's necklace playfully. Dog does not understand playing apparently. And it turns out as long as he does this on my friend's property, the neighbor cannot do a darn thing about it, because the dog is guarding "his" property.)
Last story about Dog, I promise. He is in love with my friend's sheltie and her chihuahua and lets them climb all over him. He also for some reason pukes in front of
the chihuahua randomly.
