Ok, this is kind of gross but I just can't figure it out...so I have been walking the dogs in the evening about 2 miles. Well, just recently Sam started doing the strangest thing. Usually he poops right after we get going but then on the second poop (normally he might go as many as three times while we are out), he will poop, then immediately sit down like something in on his butt and sticks his nose back there to check it out and then his pink thing (yes, penis) sticks out. So he just sits there for a few seconds while I am picking up and when we are ready to go, he stands up and it's like he is sway back or something and I notice his butt is kind of puckered and after a few steps he is normal again. It is almost like he may have a cramped stomach or something...Anyhow, today he did it then he pooped again afterwards but didn't do it- so strange. OH, and I also walk them about a 1/2 mile in the morning and he has never done it in the mornings. Has anyone ever heard of such a thing???
