High Tech Pet Sofa Scram Sonic Dog & Cat Deterrent Repellent Mat

We bought this because our 75 pound pit/boxer mix insisted on sitting in a white chair to look out the front window when we were gone. I started covering it with a blanket which kept it clean but didnt keep the dog out of it. I bought one of these, folded it to size and put it in the chair. I covered it with a blanket so he wouldnt think anything was different. He jumped in it twice while I was home and he hasnt been in it again. I have put some pillow on the chair so it would be obvious if he jumped up there again. Im so confident that he isnt getting back in the chair that I have moved it to in front of the door to keep him from jumping on the door. He has stepped on it twice and I dont think he has jumped on the door since. I’m not so confident in that, that I can take it away yet. Its narrow so a big dog can easily miss it when he is jumping on the door and I want to make sure its had its effect. Highly recommended.
