I think what we all need to see is to train a Siberian to be off lead is a much bigger ordeal compared to a Border Collie or German Shepherd. Whilst for them practicing recall in the traditional sense often is "enough," with a Siberian there is a whole other equation to work with. If you plan to train your Siberian to be off-lead, it's going to be a serious process which you must be committed to working with daily and always reconditioning and proofing. The fact is- for most owners this is not practical. I am totally fine with just letting them off at parks and other enclosed areas. We practice recall daily and I train it using their prey drive, but I do not practice it and reinforce it to the point of which I am comfortable letting them off the lead when there isn't a fence. That's not because i'm lazy or because I think they're incapable... I just don't have the need to put that much effort into having an off-leash Siberian. It doesn't matter that much. I have called them off of a flock of birds, ducks, and squirrels so it's there if I need it. For those of you who have not put as much effort into your off-leash Siberian as Bec has described- you are doing an injustice to your dog. And what you're doing is dangerous.
