If you feed your dog before taking them for a walk or other exercise then the dog can develop bloat so it's best to take them walking after eating but wait 30 minutes after the dog finishes eating before taking them on a walk or doing other exercise with the dog.
Bloating in the stomach is a digestive problem that can happen in all dog sizes but mostly large dog breeds and the bloating causes your dogs stomach to swell up like a balloon so wait at least 30 minutes after the dog eats before going for a walk with your dog to avoid digestive problems and bloating.
