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

I have had this for over 2 months now and it is working great. Our English Coon Hound no longer gets on the couch.This is easy to put in place when not using the couch and easy to remove when you want to use it (especially compared to 2 baby gates with 40lbs of weight on them).We went through all the tricks to keep the dog off the couch and this is the best and easiest to use.First we tried draping a cover stretched out at an angle from the back to front. The dog simply climbed onto it and pushed it down. Covers didn’t work because she would move them and still get hair all over the couch.Next we put stretched out baby gates across the couch. She pulled them off the couch.We then tried plastic carpet protectors with the little spikes up. Again the dog pulled it off.We went back to the baby gates but put 4 10lb weights on them. This worked for about 5 months, or so we think. This fall noticed that the gates didn’t look right and were finding dog hair on the couch. She was laying on top of the baby gates since she couldn’t pull them off.Last we got the Sofa Scram.First day we noticed some disturbance at one end of the couch but it looked like the dog had started to get on the couch and then got off when the alarm was activated.For the past two months we have not seen any sign of her being on the couch other than every couple of weeks the mark (indentation) from a paw as if she is testing it.The dog does not like the sound emitted. I found this out for sure one day when I started to remove it without turning it off.The high pitched beep made her jump and to into her crate.For your reference this is an English Coon Hound that weights 80 lbs.
