Dog with a bone

[daftyburd]

Trying my 11 month old puppy on the BARF diet. His breeder had him on Royal Canin puppy food and we kept him on it with no ill effects. Moving him on at 10 months to adult food was not so easy. He had the runs constantly and seemed red around the eyes and muzzle.
Finally decided to try BARF. He has been on it for a week and good solid poos and redness calmed down. However I tried him with a meaty bone on Friday night and his personality changed. He has never been food possessive before (cats and another dog in house) and he shares his toys quite happily. He was also fine with chicken wings but he growled at me when he had this bone and gave me a warning bark. I wasn't anywhere near the damn bone. Luckily my DD was not in the house.
Its going to be hard following BARF if he cant have bones. Would I be better to crate him if I give him a bone? Any advice about his would be appreciated.

I always give my dogs bones outside, and I leave them to it. Once they've had a really good nosh and removed most of the bloody goodness, they get much less bothered about hanging on to it. However, I've never taken food away from my dogs or bothered them while they're eating. I might drop something extra into their bowls sometimes, though. The DC have been trained to ignore a dog while it is eating, and to not approach a dog eating a bone in the garden.

I have 2 bitches and a dog. You can take the bones of the girls no problem but not my boy. The way I solved the problem was by buying chicken legs or thighs and cutting it into chunks and feeding the bones in their bowls. He is not as possesive that way. I use human grade meat as imo it is better than what you get from the pet shops as them chomping on the bones is better for their teeth than eating it ground. I can feed my three dogs for £2.50 a day and they weigh 14kg, 20kg and 25kg.
