I recently started my very pick lab mix *she seriously prefer kibble N bits* on Instinct Rabbit dry food. She seems to really enjoy it but it is giving her the worst gas I think I'v ever smelled. So bad that I actually had to kick her out of the living room last night. Prior to the transition to Instinct she was on Prairie and never had this problem. Is this pretty common with grain free foods? Anything to out there to counter act the gasiness?
