iv fed barf for a while now mate, a few diffrent dogs on the diet, had pups born an raised here on it an never had a problem, pups fed anything will do the lap of honour, throw there catch up in the air in excitment an just mess about after the first few catches, thats just pups for you, they soon settle, iv only ever had 1 dog that tried to eat the catch before i let them an that was an bitch who was a decent bunny dog, but when she hit 5 she turned funny in a few diffrent ways, 1 way was she used to swallow baby bunnys like a python on the way back to me during our evening mooches in summe
