Okay so training Isabella has not gone as plan. I'm doing the pee pads until she gets her all her shots, just because I live in a Apt and I don't know about other ppls pets. Well my coworker gave me some of her pee pad because her dog never used them. Well Isabella doesnt either she did in the beginning now she just sits on it or tears them up along with her cat bro Sonny. Anyway Petco was having that sale online so I ordered a different brand of pee pads..Nature's Miracle. I hope it works. Do you think it matters the brand??
