I was just wondering if there was any such thing as a dog marking it's territory by pooping. Kaiser eats canidae and usually poops 2-3 times a day, and it's always solid. His problem is when we get out to the dog park or the neighborhood park. I know he doesn't have to poop and he will poop like 4 times. The other day at the dog park he pooped when he hadn't even eaten his breakfast. Also, when he forces it, it's sort of runny and i have a hard time picking it up. I'm just wondering if there's anything i can do, because i hate letting him off his leash if i know he's instantly going to go poop!
