Im sorry but I have to agree that the doggie door is a bad idea unless the pup is supervised which I know you said you cant do. This is the play pen that I bought for my newest pup and it comes in different sizes and I LOVE it!!
Amazon I am able to leave the house knowing that I will not come home to a mess but most importantly I know that Armani is SAFE. My breeder used it also. I know you feel that some people may have given you a rude response but people have their own opinions and you just have to take the advice given and in the end make your own decision. Good luck and I hope you find a solution that keeps your pup safe and your floors clean lol
