Thanks for that. I've worked out it would be just under two weeks for him to eat the lot so I'm starting to think it will be OK as long as he's happy with it and he stays in good shape.
Yes we are using this food so it wouldn't be a change in diet for him. We'll certainly be checking the condition of it when we need it in a few days' time. Thanks
I never have either but I buy only small bags by choice now, either 2.5kg or 4kg, and order more frequently direct from manufacturer
