fed processed food (sack) for many years to many dogs that we have had pets and working breeds and running dogs .but always seem that 1 dog could not get on with 1 sort and then changed food only for them problem to change dogs , either hyper ,skin complaints, sh~ts, gagging when eating ect ect. after a chat with the owners breeder of our vizsla they feed there dogs raw , asked them a lot while I was there and then trawled the net for more info.
now I feed all 3 dogs on raw the sprocker, viz and the old gsd eat rabbit fur on, tripe, venison ,chicken, lamb and offal ect not found a meat they cant eat, mixed with veg fish eggs pasta fruit there is so much to choose from to change it around from day to day. as for supply ask around fish shop, butchers, local market, on-line. its as cheap as you make it. I shoot my own meat catch my own fish, buy 18kg of chicken necks £18 and tripe 50p a lb .cost me about a £1 a day to feed all 3 of them.
it took a while to sort out how much each dog needs to maintain a good working weight as the is no **** in there diet to bulk it out , but can say my dogs have never looked so well loads of energy and gr8 coats, skin and teeth. .bit of work and time but well worth it .search" barf diet" on-line
