I got some recently in an emergency as I'd forgotten to stock up and pets at home was open late.
Ddog has probable allergies and we are avoiding chicken and beef as most common allergies. We usually get the big chubs from local pet shop or trays and defrost and chop up.
I have to say the small chunks of nature's menu was s really appealing - quicker to defrost, easier to store. But is it rubbish? I've seen conflicting stuff online.
