Sable Keeps biting the necks while playing. Help???
Sable (6 months old- 55 pounds) : While playing with dogs, she'll bite the collar and try to flip them over on their backs, she will even sometimes try to drag them by their necks. I HATE THIS HABIT! The dogs don't seem to mind, but when she becomes 100+ pounds I'm sure that will change. I interfer when she starts doing that, saying no, and bad. I'll even put her in time out. It doesn't seem to work tho. Any ideas?
