He will poop outside, but won't pee outside. He will hold it until he gets home, so he can go on his puppy pads. I got rid of the puppy pads, because of this. I noticed he won't go anywhere he smells another dogs pee or poop outside, and that's almost everywhere in my area. He won't poop in the grass either. He likes to poop on the sidewalk or on dirt where the grass is completely gone, and he doesn't smell another dogs poop or pee there. When I got rid of the puppy pads I bought a piddle place but he refused to use it, and would just go in secret places around the house. I switched to feline pine original non clumping cat litter. He will poop in the litter box, but won't pee in there. He just started to pee on his beds. I took them up to see if he would pee in the litter box, and I put him in his playpen overnight, and made the area small so he would have to pee in the litter box too. I woke up, and he pooped in the litter box as usual but peed on the floor in the playpen by his food, and away from his toys. I could go back to using the pads, because he doesn't have any accidents when I use the puppy pads, but I think the scent in them is making him hold his pee to go inside on the puppy pads and not outside. Weird!
