I know what your going through and it is very frustrating for sure.
I never knew yorkies could jump like rabbits. He jumped the gate in the
kitchen and chewed up a rung on the dinning rm chair. I added another
gate and he was miserable and I bought every contraption under the sun due to his baking when I left in the am. Living in a condo we could not have that! He won and I then left him in the open house. Hence 13 throw rugs later, all corners gone he started on the corner of the skirt on the couch. When I saw that I lost it.
I really think I scared the crap out of him because he never touched another things after that, however, I did spray bitter apple all over the house. Better late than never. Someone told me about it after the fact but it saved his life! He was then 1 1/2yrs. Until the other night, he chewed the arms off my glasses, he has touched nothing! Carol & Buddy
