Hi there,
I have a gorgeous 18 month old Sibe, & I really would recomend taking them to group training, Start as soon a possiable by enrolling in a puppy pre- school.
I will pre warn you, the group training is HARD, they are very clever & very stubborn dogs, & are very easily distracted, which is why I have found them invaluable, as she has learnt to concentrate on her comands, even in the presance of hundreds of dogs. you do need the patiance of a saint, but it is well worth it, You will also need to do a fair bit of work on the training every day though,
Being a pack dog, they tend to determine who their 'Pack Leader' is from a very early age, so I would recomend that you involve all members of your household with the pups training, this will help establish the pup's place in the 'pack' & should help to elimimate some alpha issues.
Good Luck
