I am sorry but i agree with the chain thing. While i have not owned pitbulls my own self, i know many pitbull owners
who use braided steel cable like the shit that comes in winches and then they have it plastic coated so the dogs cant fray it and get stuck with wires. Shit works great. I have 7 GSD's with Czech, German and Full American lines. Most big name breeders do not use chains like you say they do and if they do then they do not have adequette kennel space and shouldnt be overcrowding their area. You have beautiful pups but the "incident" kinda has me concerned but it does show that you care a little with the way your getting defensive.
Also, you can get better food for a lot less. We feed all of our dogs from our pups to our pets and breeding femals all Kirklands best from Costco. Its a great food and it doesnt contain a lot of the fillers and more "less needed" ingrediants. I forgot which ones those are at the moment but i have a bag of Pro Plan downstairs that i can look at to tell you which ones are not good. If you are interested in this you can PM me. Also if you want to hear about the condition of all of our dogs and our reputations, i can give you the number the the Vet office that sees all of our animals and numbers for people that have bought our dogs. Kirklands is proly one of the, if not the best food on the market but people look at it like the cheap shit at foodlion. There is a difference.

I highly suggest looking into some lighter cable for your dogs and GLWS.
