Yes, Sequoia is really a beautiful husky- nice markings. Before having Sherman, we had star and a rottie-mix female dog about 4 yrs. younger than Star. They got along ok, but once Rosie grew up there were some REAL battles - lots of blood, ugly. After Rosie was killed by a car last spring, I contacted husky rescue & breeders before getting another dog because I didn't want to go through all the fights again. Star is a dominant female (ahem, the Queen of everything) and I was told that a male would be a far better choice. Sherman's breeder said she thought huskies do get along best with other huskies, partly because they have a different pack dynamic. (The alpha is on top, then #2, #3, #4 etc. whereas other dogs might have an alpha and then all the rest equal. I don't know if this is true or not, but having just added our third husky, I can see Sherman definitly claiming his right to the #2 spot). Huskies do sound "vicious" when they play - lots of growling, and they play rough. When they tuck & run I call it "skootching around" - its so fun to watch! Star and Sherman raise their hackles when they get excited, not when they're mad. As for prey drive, I trust Star with my old cat because she was raised with him, but I don't trust the others. And Star has killed literally dozens of birds, squirrels, raccoons, possums, and even a skunk that got too close. It's quite amazing to see how efficient she is- what a good provider she'd be if she was on her own! Also, Star can be off lead, she's pretty obedient, but Sherman and Cloud will probably always be leashed in public- in fact, it was written into Sherman's adoption contract.
We live in Northern Ohio, so our weather goes from about -20 F to occasionally over 100 F, and the huskies tolerate it well. Mine live outdoors year round. They just don't do a heck of a lot during the summer, and like to dig pits in the ground in the shade. I feel like things have worked out extremely well with more than 1 husky, better than with 1 husky and 1 other breed. Lots of people have other combinations that work out well. But I'm glad I took the husky people's advice - I love my little pack! (My husband said he thinks I'm trying to sneak in a sledding team!)
