IMO. Kennels are the only way to go unless you have a lot of dogs which might make cost too much. I have seen many dogs get to territorial when chained up most of the time. Also a kennel run is easier to clean and keep clean for parasite control. One more thing is that I have too much time, money and love tied into my dog to let him run and maybe get hit by a car. I have never had a dog killed on the road but when I have talked to others who say it is cruel to keep a dog locked up and later come to me crying because their dog just died on the road. Mine are with me when I am outside but when I am not home they are in the kennel.
