Common, my dog is a Xoloitzcuintli and I've gotten serious about modifying some of his behavior. I have found a lot of resources on the internet and some interesting videos on Netflix. Diego, as a feral breed, is totally lacking in the doting-on-humans gene that present in dogs bred by humans to serve humans so he's a challenge but his behavior can be modified.
If I figure out how to eliminate his phobia of snare drums I'll get back to you. Unfortunately, I live in Mexico which may be the drum and bugle corps capital of the world.
No, my daughter had a wolf. Now that animal was wild. Diego is more independent. I was trying to teach him to fetch so I could exercise him while I relax. I put a 25' leash on him and threw his toy down the longest hall in the apartment building. He ran and got the toy, which he always does, but didn't return. I reeled him in. Then I threw it, and he returned with the toy. I threw it a few times and he kept bringing it back. I thought, "This is easy." Then I dropped the leash and threw the toy. No problem. He brought it back. We did this a few times. "Wow, he learns quickly." Then I unclipped the leash from his collar and threw the toy. He ran and got it, came running back, jumped over me sitting on the stairs, ran up the stairs, into the apartment, hid the toy, and was relaxing when I got up there. I could distinctly hear him say, "Screw you."
The problem is that making me happy is no more important to Diego than it was to my ex-wife but Diego isn't malicious. My kids had a shepherd mix and he lived to make everyone in the family happy. Different breed.
