Sheila's nipping is getting out of control. We have tried everything I know and have read here and elsewhere. You ignore she jumps you from behind, grab her by the collar and tell her a firm deep NOOOOOO works for seconds, putting her in a dark lonely place with no toys, works for a few minutes after release. It is really getting down right annoying. I believe it is all in play even though sometimes she growls when she has her tantrums. I figure if she wanted to, even at 6 months she could break skin if she really meant to as the can sure as hell hang good from her spring pole. But I am at my wits end. Worst part is when we go to puppy class she is the best behaved, most obedient dog in the class!!!!!!! Am I not using enough treats??? Should I carry treats with me at all times and lure her away when she starts jumping and nipping????? I also read somewhere that if your dog nips at you, you should ignore it for a few days. It does not specify if it means only affection or affection and play???? Do you just feed, exercise, discipline and train your dog and ignore her at all other times??????? I feed her by hand which gets her attention while eating, and obeys all her commands quickly, stay, sit, down, roll, bed, catch, fetch and a few more, but once the food is done its like she forgot everything!!!!!!!! The nipping is starting to concern me because she is just at 6 months now, and I am hoping it is just a phase she is going through, cuz she is getting mighty strong quickly. ANY OTHER TIPS or advice I am open to, just don't know what to do anymore when she gets like this.
