Dog constipation is what happens when your dog just can’t go.  Try as he or she might, the bowel movements just won’t flow.

From the dog’s perspective, this must be particularly confusing.  “I’m trying to poop, but I’m just not pooping.  What am I, constipated?”

Given estimated canine intelligence levels, it may be more like, “arf arf arf, arf arf arf arf arf, arf arf arf arf arf arf arf!”

But regardless, they are still constipated.
