How often a dog should be walked depends upon a number of different variables. You need to factor into the equation how old your dog is, what their activity level is like, what type of energy they have and what kind of dog you have.
Those several variables will also factor into how long you need those walks with your dog to be. The idea of a walk is very different than simply taking your dog out to relieve themselves. A walk should give your dog the opportunity to release some of their pent up energy and exercise as well as to relieve themselves.
Owners typically complain about how their dog is destructive during the day. Perhaps their favorite shoes have paid the price or their furniture winds up with canine tooth marks all over it.
The first thing that a behaviorist or dog trainer will ask you when you seek their assistance with your unruly pooch is how much exercise your dog typically gets on a daily basis. The reason that this is important for them to know is that dogs who are bored and who have pent up energy tend to exercise these destructive traits.
You need to walk your dog long enough each day so that they burn off that pent up energy each day. If they walk long enough every day they will not feel the need to become destructive because their energy will be spent. A tired dog is a good dog, this is important to remember. You don’t want to walk them so much that they are exhausted but at least one good long walk each day is probably reasonable for most average dogs.
If you have a dog with an extremely high energy level like a Border Collie or a Boxer, you might need to spent a little more time wearing them out if you want to keep them satisfied. Two long walks a day and a shorter one in between is probably a good idea for a dog with higher energy and you may also want to run them in the yard with a ball a little bit so that they are really tuckered out.
Also, if you have a smaller dog like one of the toy breeds, you will need to take them out more frequently to relieve themselves as their bladders are much smaller than larger dogs. Senior dogs also need to go out more often as they have trouble holding it.
