Alot of new people, well, people in general do not beleive in putting a dog on a chain. My input is, if you have only one dog, keep him inside, if you have more than one, put em on a chain.
I dont mean that as in just a chain, my setup is half chains and the other half 20 ft. kennel runs.
I DONT beleive in using monter size chains, there just no reason. Put a nice size chain that your FOR SURE will hold your dog and stick with it.
