Hi, I have a 13 week old bullmastiff X APBT who is a real little charmer. Stubborn little b-----r though, he has complete food 2 meals a day and raw meat or fish the other 2 meals and he's worked out if he skips the complete meals I worry he'll grow up midgety and feeble so I give him a bit extra for the raw meals. Mixing the complete with gravy etc. makes no difference. I'm getting old - I never used to worry about my other dogs like this, they either ate their food or did without.
I'd love to see a picture!
