Dear Lucy,
It is nice to read that many pet parents, like yourself, are researching to choose the right nutrition for their pets. This indicates Spunky is clearly loved and well cared for. The quality of what we feed our pets directly influences their health and vitality. I don’t have personal experience with either brand, but I have some general information to share.

Open Farm is celebrated for its transparency and commitment to ethically sourced proteins and sustainable practices. Their recipes often feature a variety of protein sources, including less common options like venison and fish, which can be beneficial for dogs with specific dietary needs or sensitivities. Additionally, Open Farm provides detailed information about their ingredient sourcing, allowing pet parents to trace the origin of each component in their dog’s food.

Performatrin Ultra Limited Ingredient diets focus on simplicity, offering recipes with a single protein source combined with limited and easily digestible carbohydrates like sweet potatoes. These kinds of diets make feeding dogs with food sensitivities or allergies easier, as when you know what triggers them and also know exactly what a food contains, it minimizes the chances for adverse reactions.

Each of these brands offers a range of different products and ultimately, the best choice depends on Spunky’s specific health requirements, preferences, and any known sensitivities. Since our goal is to be the most useful resource for pet parents, at Dogster we have hundreds of free-access educational posts in the topics of nutrition, understanding food labels, considerations, and recalls as well as food reviews. Observing how Spunky responds to a particular diet is essential, as individual reactions can vary. If you notice any adverse signs or have concerns about his nutritional needs, consulting with a veterinarian is recommended to ensure his diet is the best for his health and needs.

If you need personalized help navigating the labels or understanding why a dog might react to a certain diet, a one-on-one video call with one of our vets on our sister site, Pangovet, and they can help guide you and answer any questions you may have. Again, congratulations, choosing the right food for your dog is the most proactive approach a loving pet parent can have.

Warm regards,

Dr. Paola
