Caloric Restriction for Canine Healthspan & Longevity

Research spanning a landmark 14-year controlled study and over 50,000 companion dogs confirms that caloric restriction is the single most powerful longevity intervention available for dogs — keeping dogs lean extends median lifespan by up to 1.8 years and delays the onset of chronic disease by two full years. Dogs fed once daily show up to 59% lower odds of liver and pancreatic disorders and a measurable cognitive age advantage over more frequently fed peers. Yet with 65% of US dogs currently overweight and most owners unaware of it, the gap between what the science says and what happens in the food bowl remains the greatest unsolved challenge in canine longevity.

Mattress Walking as Canine Physical Therapy & Strength Training: A Scientific Breakdown

Walking your dog on a mattress or any soft, unstable surface is a scientifically validated physical therapy modality that simultaneously fires proprioceptive pathways, recruits more muscle fibers, and strengthens the core — all without adding a single pound of extra stress to aging joints. Backed by peer-reviewed EMG and biomechanics research, just 10–15 minutes of mattress walking several times a week delivers the neuromuscular benefits of formal canine rehabilitation, right in your own home.

Creatine Supplementation in Aging Dogs: A Narrative Review of Bioavailability, Efficacy, Safety, and Longevity Applications

Most dogs fed commercial diets are functionally creatine-deficient due to the near-complete destruction of dietary creatine during high-heat pet food manufacturing — a critical and underappreciated nutritional gap with real consequences for muscle, brain, and heart health as dogs age. Emerging research demonstrates that creatine supplementation in dogs improves high-intensity athletic performance, combats age-related muscle loss (sarcopenia), protects against cognitive decline, and supports cardiac bioenergetics, making it one of the most compelling multi-target longevity interventions available to proactive pet owners today. This review synthesizes the current evidence, identifies guanidinoacetic acid (GAA) as the most stable and bioavailable delivery form for creatine in commercial diets, and provides practical, veterinarian-informed dosing guidance for senior, athletic, and at-risk dogs.
