I think I know.
Same place mine get theirs. But they bring such joy, don't they? I currently have one dog that we've had now for 4 years, and it's just been in the last 6 months or so that he's fully relaxed and decided he can trust humans. Well, at least me. He's a Pyrenees that was raised wrong... but after all the work I've done with him, trying to make him understand I'm his friend, not his enemy, when he looks at me with his silly goofy smile, and his tail lifts and he gives me one little wag... my heart swells. I can't wait for the day he lets me actually hug him. He's a dog that NEEDS huggin'! LOL! (The truth is,
I need to hug him, I love him sooooo much!)
Have one, Grouch's brother. We've tried very much so to get him relaxed. He is Pyrenees with Lab and it seems more Lab. He is skittish & high strung, which translates to him lashing out at other dogs. Do not think it is a matter that he is aggressive per say, but this is what it goes to.
All the other dogs have sensed my calmness, (which I do diligently maintain ) and see that I let my wife be "big dog" most of the time. They also sense and know I am a "big dog" too but a relaxed one. I have to stay relaxed as stress and anger do me no good at all. I am aware of that and do take responsibility in it. Dislike much so being frustrated that I cannot 'reach' Lock, Grouchy's brother.
You do find dogs that are naturally high strung. I do not get abusive with him. Nor do I play favorites with the other dogs, over him. All of my dogs and even our cat know, Papa loves them all, each one as they need loving. Each gets a turn or two seeing Papa for a few minutes. My wife treats them the same. We do discipline them as best we can.
We both have seen Ceasar and both try to follow a similar way with our critter family. We also know though that life, people are not always perfect. We know too that sometimes spades are spades. In Lock's case he's simply naturally high strung. I feel he would make an excellent hunting hound for someone. At present, I do not hunt ergo do not work him as a hunting dog. I know if someone did, he would run down some of the excess anxiousness he carries.
As it is, not sure I could get around that anxiousness to get him interested in working like that. This is where the actual act of hunting would fill that void. Ah, well love them all.
NB: To clarify, as soon as we can again get him to where we can approach him, put a collar on him and get him ready ... Lock will be going to someone that adopts out dogs to good homes. She will find him a matching hunter to go hunting with.
He has had rabies shot, been neutered. It was a 'fun' day getting him to the vet for that. Fellow weighs around what a rectangle bail of hay weighs, 76 lbs. Had to carry him into the scale, then, back to the pen for the vet. He was terrified and 'shut down'.
