Not all, I tried him with some tuna and he wasn't bothered, he's been eating spratts mind, loves them, same as chicken feet.
I've been keeping it consistent with the beef/tripe mince and just keeping some kibble down that the Akita feeds on.
The pup being around and coming on the scene has actually started making the Akita eat more, the competitive pack mentality must have kicked in. Lol
