Dude, I had a wolf/husky hybrid growing up. He was amazing. I want another one, but the restrictions where I live now don't allow them. I would recommend a hybrid to the OP, but we had to shave our boy in the summer to keep him from being too hot/shedding allll over the place.
I like Australian Shepherds, they're very pretty and reasonably smart, but IDK if they could keep up with you on those kind of treks.
I will have to look into the research about the spay/neuter. That is most curious, I read something else brief on this subject before, but I need to do research now, and look in relation to cats too.
Also, there is much worse Kool-Aid, like the PETA drink...
Agreed.
