These dogs cackling, amazing in and of itself because most of us now know that they have the ability to mimic sound. They must be motivated by their owners. Dogs are affectionate animals. I searched for a wolf but I don't think any would ever be available. I doubt they would ever stoop to please a master, most are Masterless. That's the way they like it. Wolves are superb friends to have in the wild. They are loyal and intelligent. They don't tolerate pleasing a human just to please him. That's why I love them more. They are free and independent spirits. Of course they are predators, that is their calling.
Which is not to say I am not fond of dogs. I have had quite a few since childhood.I used to communicate with Dvorak, my Komondor without speaking. Yes! he could read my mind. Any man I found overbearing and drunk, Dvorak would tear off the cuffs of their trousers. If you have ever seen a 130 pound Komondor, one meter high covered in curly white wool with canine teeth like scissors, you would sober up pronto. In the steppes of Pushta, Komondors guard sheep and horses against bears. Wager on the Komondor. They usually win their battles against bears who would dare to attack their sheep and horses and cattle entrusted to them.
