If that isn't a Husky crossed with a polar bear I'll eat my hat !That's a big ball of fur!!!
Could just imagine the sweeping and vacuuming with that doggy around the house.
Don't recognise the breed though.

I'm still taking guesses here as to what that huge, floofy Husky is mixed with - I see Malamute, and maybe some Newfoundland, Great Pyrenees, Mastiff, and Samoyed thrown in for good measure...
Hope the owner keeps their Dyson charged 24/7 !
