Hah

your'e asking the wrong person here about food I'm afraid :D all I know is what I feed or would feed my dogs. For a dog your size, imo only ;) I would feed a medium sized tin and add mixer BUT whether he would need or want the mixture I truly don't know.
I used to feed a complete (autarky) to both my girls before one got epi/allergies and the other one decided she wouldn't eat it cos the other one, in her opinion ;) was getting better food i.e nature diet but then had to take one off that and so to cut a long story short, I decided going raw was the best option cos at least then I knew one of them wasn't getting any 'hidden' ingredients that could affect her, and the other was quite happy that she wasn't missing out :D
Sorry I can't help but as I said, epi shouldn't stop Tyler from eating whatever he wants.
