My Coco is already 20 months old and occasionally, she will pee on the bed. Is this natural. I thought they are very clean dogs and will not dirty their bed. Sometimes, she confuses the hell out of me. As my instinct (like the suggestions here), I will not put water after 8:00 p.m. but my Cody only drinks a little bit at a time, and he is sooo good with going to the pad (both pee and poo) and I am afraid he is not getting enough water and maybe thirsty as he goes to the spot where I put the water (after I have taken it out). Any suggestions for older dog. My Girl is the one who can't hold her pee at night eventhough we have taken her out (in the freezing temperature) to do her business. Any advice anyone.
