Thanks for the pun :) hehehe
Good luck with yours too!
PS: I agree about the very high carbs in Burns.
I am no expert but maybe the dog adjusts to that and utilises the carbs over time? My one and only experience with Burns was when I visited some friends and forgot to bring enough of my dog's own food. I found a shop selling Burns so he had the Duck one and the venison one for about a week. I hope you're not eating your dinner when reading this, but said friends had a fairly persistent rat problem on their land.... I realised exactly how much carbs there were in Burns when I saw rats snacking on my dog's poo -

- well that is not normal.... obviously a lot of that carb is being excreted and not used by the dog at all but serves as filler or fibre. Unless the dog starts to use that over time, then it really is poor value for money.
