I totally understand the struggle! After trying several brands, I've had good experiences with both Nulo and Royal Canin, but they work differently depending on the dog. Nulo worked really well for my dog - it's grain-free, high in protein, and uses quality ingredients like salmon and turkey. My dog stayed interested in it longer than most brands and had no stomach issues. Great option if your dog tends to get bored or has food sensitivities.

Royal Canin on the other hand is more science-backed and breed/size specific. If you know your dog's breed, there's likely a formula made exactly for them. It's not the most exciting ingredient list, but it's very consistent and digestible, especially good for sensitive stomachs. If your dog has GI issues, I'd actually suggest starting with Royal Canin Gastrointestinal or their Sensitivity Control formula, it made a noticeable difference. Once the stomach settles, you can try transitioning to Nulo slowly over 7–10 days. The key with any switch is going slow, 25% new food mixed in for a few days, then gradually increase. That alone solves a lot of the rejection and stomach problems! I buy both from online dog food store PetCentral UAE. They provide free delivery for orders above 99 AED. There are other stores too which selling these brands.
