"Ater getting our West Highland at about 6 weeks old, we brought him home and set him up with his own area in the kitchen with his food, water, crate, and pad and sectioned him off with one of Petco's excercise pens. It took him a while to get the idea of urinating on the pad, but eventually with treats he began to learn. The problem is.. he only did it while we were home. Every day we came home from work, we came home to a disaster. He would rip apart his pad and 'go to the bathroom' where ever he chose, not to mention walking and laying in it. I was giving him a bath every other day, if not every day. He had toys to play with, but those ended up needing washed each day also.
I came to this site looking for some help and upon reading the reviews for this product, I was sold!! We plugged it in right above his little area at about chest height. It's been about a month now and we've witnessed NO change in his behavior at all. He still makes a disaster each day. He still whines until told "NO", but will then continue 10 min later. He was never much of a barker, thank goodness.
I'm sorry to disagree with the majority of people on here, but I would NOT recommend this product and I will NOT be buying a refill."
