We are looking at buying two Siberia Husky female pups as family pets. We have read that they have a tendencey to run away. As a result, my wife is concerned that we would never be able to keep the dog off a leash other than when roaming in our fenced in yard. Is it really true that, no matter how trained, Huskies should never be off a leash and is their propencity to run (ie. run away) so strong that it should deter someone from getting them? Any help would be GREATLY appreciated.
