i honestly have nothing for you that wont offend someone. My animals are my fur kids. I couldnt imagine my life without them. My kids get very upset when the animals arent with us for a little while so i know their take on it as well. My husband would be perfectly fine if we never had another animal in the house despite the fact he does like them. They're mine. Plain and simple. We have pets because i wanted them. He wants to get rid of them or dwindle it down so we only have one. In all honesty, if i wasnt able to bond with an animal i would rehome that animal. If there isnt a bond, there isnt really much of anything except that distrust. You may very well just be the messanger to get him to the right owner that he can bond with. He will take a great deal of work. The husky side of him is the side i'd be more concerned with because of that independence. That whole whats in it for me instead of what can i do for you attitude is why husky's in general are the ones who are perfectly happy to run off and survive on their own. I might suggest that if he and your GSD cant get along and share, it might be best to rehome him as an only dog in a family without kids because those kinds of negatives can impact your GSD and how he behaves around other dogs as well. Riley growls at Shasta when she walks past him when he has something. He gets in trouble and the object is removed. Its not acceptable. Zena was/is female aggressive. She's a very dominant girl. She was forced to learn that her aggressive behavior was in no way right or allowed. As long as someone doesnt start anything with her now, she's good. Do what you feel is right. Some of the issues i'd be willing to work with him on but that aggression whether it be fear or just generall aggression, i couldnt have in my home because of my kids. He wouldnt be able to go on walks or anything because this neighborhood is loaded with kids. Its up to you if you have the desire, time and energy to try and work with him but you'll always have that fear in the back of your mind that he'll do something to become a seriously liability. Its something you need to sit down and seriously think about. he can be worked with but can he be worked with by you? Not saying you're a bad trainer but you may not possess the knowledge to handle it.
