Posted 08 May 2009 - 12:45 PM. A potty walk or a stroll, even if long, doesn't count as strenuous exercise. You can take your dog for a potty walk or gentle stroll before/after eating. A power walk counts as strenuous exercise. You can take your dog for strenuous exercise 2 hours after eating. My rule for feeding after exercise is to wait until the dog is recovered -- no longer panting, etc. Really strenuous exercise like a hard run, the 2-hour rule is a good one.
