When we first switched our dogs to fresh food, we noticed something that’s become a more common conversation point than we ever expected in our lives – firmer stools! A few other immediate differences too – a shinier coat, more energy, fewer digestive upsets, less anxiety and we’ve learned, far, far fewer vet visits!
Studies have long shown that minimally-processed fresh food diets for dogs, just like for ourselves, are highly digestible, allowing for better nutrient absorption. They also increase microbiome diversity, reduce pro-inflammatory proteins in the body, improve appearance and demonstrably contribute to a longer lifespan.
Science has been confirming what fresh-feeding dog parents have been witnessing for years.
A new 2025 study* has further bolstered the evidence. Over the course of a year, researchers followed senior dogs fed a fresh, human-grade diet and found some remarkable benefits:
Ready energy
Dogs burned fat more efficiently, giving them lasting fuel throughout the day.
Stronger muscles
Higher levels of amino acids and creatine supported healthy muscle maintenance.
Less wear-and-tear, more protection
Lower levels of compounds linked to ageing (AGEs) and higher levels of antioxidants like ergothioneine, carnosine and anserine help protect cells from damage.
Healthier fats in the blood
Omega 3s – essential for joints, skin and coat – were higher.
Steadier metabolism
Markers suggested improved overall metabolic balance, supporting consistent vitality as dogs age.
In short, fresh, minimally processed food doesn’t just taste better, it supports metabolism, vitality and overall wellbeing as dogs age.

A gentle reminder: every dog is unique: breed, lifestyle, environment and genetics all shape how they respond to food. Diet is a single part of the bigger picture. Regular exercise, vet check-ups, a safe healthy environment, mental enrichment and plenty of love all matter deeply too.

*The 2025 study https://www.mdpi.com/2218-1989/15/10/676 used a very specific diet, so it’s not exactly the same as Phoenix Bark, but we like to discuss and consider high-grade, minimally-processed fresh food and lower-grade highly-processed; and for adding to that understanding, the research is highly valuable.
It focused on senior Alaskan sled dogs fed a specific fresh, human-grade diet and was industry-funded. While not identical to Phoenix Bark’s recipes, it’s another piece of data that adds to the growing body of compelling evidence showing that gently cooked, wholefood diets support healthier metabolism, stronger muscles and more balanced energy as dogs age.
What it did show is that fresh, gently cooked meals support healthier metabolism, stronger muscles, more antioxidants and balanced energy in senior dogs. At Phoenix Bark, we use wholefood ingredients and no synthetic vitamins, ensuring optimum bioavailability.
