Canidae Merrick pet food comparison

With thousands of dog food products to choose from today, it can be hard to know at a glance which brand or recipe is best for your pup’s health and wellbeing.

We know you want the best for your pet, so we created a series of posts to help you compare Canidae® ’s pet food products with other leading brands – based on specific nutritional criteria. This post will focus on Canidae PURE Salmon and Sweet Potato compared to another leading brand.

Why A  Salmon-Based Diet is a Good Idea

Some proteins, such as salmon are very nutritious for dogs when prepared in the right way. Salmon is a great source of omega-3 fatty acids, which support the immune system, may decrease inflammation, and can keep your dog’s coat looking shiny and healthy. It’s also a good protein source. Undercooked or raw salmon, on the other hand, can be dangerous. Therefore, choosing a pet food formula from a trusted brand with salmon as one of the key ingredients is a very good start.  

Now, check out our comparison of Canidae’s Pure Limited Ingredient Grain-Free Dog Food With Salmon and Sweet Potato with Merrick Grain Free Limited Ingredient Dog Food With Salmon and Sweet Potato – based on several nutritional criteria, which explains why we believe Canidae’s vet-formulated pet food overall offers your dog a more nutritious meal. 

We always recommend you ask your veterinarian for dietary advice if you’re uncertain about how best to feed your dog. 

Also, remember that changes to your dog’s diet should be introduced slowly – read our post for more information about how to switch your pet’s diet safely
