Should I cook or prepare canned dog food before feeding it to my dog?

If this canned food is proper dog food then there should be no problem for your dog to digest it. Dogs do not need pate'd food to be able to digest the food. Just make sure that you calculate the added canned food into her total daily intake, like you do with her treats.

If you want to cook for your dogs, the diet MUST be balanced correctly. The best way to do this is to have a recipe formulated through BalanceIt.com and purchase their supplements to use in order to balance the diet out with all the vitamins/minerals needed for your specific pet. I suggest you refer to their website. ( https://secure.balanceit.com/recipegenerator_ver4/index.php?rotator=EZ )

Canned dog foods usually have preservatives in them to prevent spoiling regardless of temperature. So this should be fine. If it is a refrigerated food then I would be concerned it may have spoiled. Especially if the cans were hot to the touch when you retrieved them.

Dry commercial dog foods are shelf stable and do not require refrigeration or freezing for storage. Store any open food in a food-grade container that seals well at room temperature. Be sure to use all food before the expiration date printed on the bag.

Food should ideally be fed at room temperature or very slightly heated - be careful heating in the microwave as the centre of the food can become much hotter than the outside and may cause burns. Placing the food bowl into a basin of hot water or heating gently over a radiator etc can help to just take the chill out of food

There are good options in each of those categories. Moist or canned does not necessarily mean high fat, nor does it necessarily mean their teeth will suffer (although you will need to be more conscious of brushing teeth or giving dental chews if they are on a canned diet). Dogs with any predisposition to urinary issues or kidney disease are actually better off on canned or high moisture food, as it increases their water intake (because of the water in the food). You can also feed a mixture of canned and dry. I recommend a high quality commercial pet food such as Science Diet or Nutro.

Yes, dogs can do very well on dry food only. It isn't that dry food is the most ideal food, simply that for most pet owners, it is the most convenient food to store, and the most affordable. There are some people that choose to feed raw dog food, or even cook all their dogs meals. In general, there are many options, what matters is that our dogs are feed a nutritionally balanced diet. If people choose to prepare their own food for their dogs, they should follow recipes from veterinarians, and not just recipes on blogs. I hope this information answers your question.
