Bests & Worsts Reviews from Amazon

I bought this the 1st of June for my small Papillion mix, adopted 2 wks earlier. Living in a condo, must walk dogs on leashes and I use a wheelchair. I did not want to go out in the rain or snow. I have 2 grass potties, one is smaller. Every morning I put my dog on my enclosed patio and said go potty. After 2 months I was getting discouraged, but after at week 10 she wewe and pooped, i praised her and was so happy. 2 more weeks it was hit or miss, but I never gave up, now September and i say go outside and she runs for the patio door. Everyday any time of day. Raining today and I didn't have to walk my dog outside. Great product,,, give it time and don't give up. I am so happy.
