> Their "Hunters Menu" nuggets are rice free.
Do you mean Country Hunter? I just used a bag of these last night and they are very good.
Re. treats if you do an exclusion diet, these must be included as well. I follow the same rules - novel foods, although depending on what I'm using, there may be grains in there but these are novel too. For example, I've made a semi-moist cake type thing to chop up using the tinned Country Hunter food (will use the nuggets next time, I didn't realise they existed when I made it), quails' eggs and spelt flour as these are all 'safe' for my allergics. Next time round I'll be trying homemade apple sauce (unsweetened, from cooking apples) in place of the eggs.
Alternatively I have chopped up sprats and semi-dried them in the oven (I find fully dried sprats not chunky enough and too flaky); I've also bought Meatlove horse and buffalo meat&treat sausages and I'm about to buy chunks of horse, boar and venison meat from The Dog's Butcher to chop up and cook for treats.
What started out as a major headache trying to think what I could use (and spending a lot of money on the Meatlove, although it is very good), I've found that there are actually a lot of options!
