I feed our older dog raw, but I don't do full BARF, just the blocks of Prize Choice or equivalent.
I've googled how much to feed our puppy Weimaraner and it works out to be the same amount as our fully grown Dalmatian. Is this right? It seems an awful lot!
The calculations I found were either 10% of current puppy weight, OR between 2/3% of anticipated adult weight.
The calculations for our older dog are 2/3% of adult weight and this keeps him at a good weight and size.
