Before I adopted Cody I was offered a 5 month old red Pit Bull. RED Pits are most fav. breed in a big dog. I had to turn the puppy down because it meant I would have had to put up a 6 foot high fence, that would block the beauty of the woods, the reason I bought this house, I didn't want to feel like a prisoner, all caged in. Now it's to late, community has a new law, no Pits, Dobies, Rotti's, Akita's no dog over 35 pounds, also, Cody is not dog friendly. Any guard dog wouldn't do any good, you do not have to come on my property to throw eggs on my deck, a guard dog would not be loose outside your property so that would not have prevented this idiot from breaking off the CB antenna. What will work is a shot gun.
