I was cleaning my keyboard last week and my little Kayla Sue started to bite on my feet. She has been the toughest puppy to train of any I have ever had. I have tried everything. I sprayed her with the Memorex Air duster which is just pressurized air in a can. She stopped and ran off. I have used it for all behavior issues since and she is improving 100 %. I can just say "CAN" and she stops whatever she is doing.
I am hoping this is the final solution to her problems. I wish I had discovered it before as she is now 9 months old and been so much work as extremely hard to train when it comes to chewing and biting. This really has done wonders....
