We have a 7 year old Maltese mix, 15 lbs, male. He loves to go on walks except in the rain. The patch is very convenient when its raining or for emergency bathroom breaks. We live on the 3rd floor of a condo building so its very helpful. We have the large patch placed on our outdoor balcony. The first patch we received was old and decaying. Once we called customer service to discuss our concern, they informed us that there was a shipping delay and sent us a replacement patch right away. Our dog took to it after a week. We rewarded him each time he explored the patched. After a week, he peed on it twice, which we rewarded him a great deal for. Putting his leash on also seemed to signal that it was a relief spot. We love the patch and will continue ordering! It still looks great after one week. Thank you!!
