My dog, a very large Saint Bernard, was not allowed on the furniture. I just had to tell her no whenever I saw her trying to get up on something or take her down when she did manage to get up on something. I got her as a puppy. My two young sons (grown with dogs of their own) would let her set in between their legs with her butt on the sofa or chair and her feet on the floor. I laughed the first time I saw this and let it continue. Also, after much begging by my younger son, Mike, Moose, the Saint Bernard, was allowed to sleep in his bed. It didn't last long because she grew fast and took up the whole bed. I checked on my sons one night at bedtime and Mike was on the floor and Moose was in the bed. I asked him why and he told me she took up too much room. I then told him she belonged on the floor, not him. lol He as a soft hearted child and didn't want to put her out because she was used to sleeping in his bed. Moose has been gone for many years and we still miss her very much. I would never use a mouse trap or anything else that would hurt my pet.
