My puppy, Daisy, has decided the travel playpen that I sometimes put her in is her litter box. She actually tried to get in it and peed on the floor when she couldn't. I had put her in it one of the first days I had her and put some blankets and toys on one side and lined the entire playpen with pee pads. I also put her in a litter box with pee pads, but if I really want her to go and get it over with I can put her in the playpen. I have been trying to avoid that, because I want her to go in the right place, but have kept the playpen in the room for when I need to keep her safe and out of trouble. eVery time she is in there she pees and poos. She has gone a few times in the litter box in other rooms and the same room, but really seems to know the playpen is where to go...when it really isn't!! I have now let the sides down so she can actually get in, so she doesn't go on my floors, but am hoping as she gets older she will learn the litterbox is the place to go. What does any one suggest about this problem???
