My Junior who is 14 weeks old totally skipped the whole wee wee pads.. I tried to train him on them because its cold here in NYC and he wasnt fully vaccinated..but he would go every where but on them... so i started to train him to go outside and he is perfect! as long as i keep him on a regular schedule he wont have any mistakes... but it is 31 degrees right now and taking him out is painful for me because its soo cold but he loves it and never wants to come inside... so for some dogs it works and wee wee pads are the best and for other dogs like mine. I did buy an 80 count of wee wee pads for 25.00.. i have 60 left .. just sitting there...
