We really recommend against it. We’ve worked very hard to protect you and your pets from contamination. By using human-grade ingredients and production facilities, blast freezing as soon as possible and all that rigorous testing. By thawing and refreezing, you might give bacteria a chance to cause mischief in your pup’s guts. Try to keep your food frozen, right up until you’re dishing it out. And if after an hour your good boy (or girl) hasn’t eaten it all up, remove the rest and clean the bowl in soapy water.
