Appropriate Length Of Walk? in Health and Medical discussion Posted March 4, 2015 I think it varies form dog to dog. I like walking my guys, I have two boys ages 6 and 4. We do an hour in the morning and an hour at night, (we try to vary our route when possible) and they get a short potty break at noon and another one before bedtime. Cold weather or snow on the ground does not slow us down though. And since we don't have a yard--we have to go for walks. My greyhounds do love to run off leash and when possible I take them to areas that are fenced in where they can really run. When the weather warms up I like to drive to different parks, or the beach or hiking for special outings. I think our walks keep them in great shape. They are well muscled and not overweight.
