I know many say use hardware cloth for runs and coop openings to protect against predators. I have to warn you though, most dogs can dig through it, as well as tear it apart with their teeth. We used it burried to keep the mini doxie from digging out of the yard ony to have him go right through it. Our larger dogs als had it secured to the kennel door so they wouldnt paw at the fan facing it, they tore rigt through it. This was 1/2"x1/2" and 1/4"x1/4" welded wire.
While I am at it, the chain link that comes with dog kennels is not strong enough to stop a dog either. They can push through it if determined enough. Privacy fences? Wont stop a cat or coon or possum from coming over. Also wont stop a dog from digging under into your yard.
Just some words of advice from first hand experience with fencing types and various critters trying to be kept both in and out of enclosures.
