Giving that most dog owners prefer to keep a dry food-based diet on a daily basis, the large containers are often used to stock dry food. Thus, if you plan on also feeding your dog wet food as occasional treats or in-between snacks, we would definitely suggest opting for a smaller-sized container. The maximum capacity should not exceed 5-6 pounds, considering that you shouldn’t feed your dog wet food more than once a day, but smaller amounts.
Also keep in mind that wet dog food requires more drastic sealing and preserving features, so choose a container made of high-quality materials that will keep all extra moisture and pests away.
