The only reason I use the diaper is that it has elastic around the edges and it stays on him better. No matter how many bellybands I tried, he always wiggled himself out of them. All he has to do is stretch and pops himself right out of it.
He does go for walks and plays regularly. If he gets really stressed and I try to crate him or put him in his xpen, he will poop everywhere. He will even go outside and mark over where my other dogs have peed. And, I do clean the areas he marks in the house with a cleaner that is supposed to remove the smell and stain, but he continues to do it.
He is a highly anxious little guy...
