What does it really take to keep our pets strong, active, and thriving as they age? In a recent episode of The Natural Nurse and Dr. Z on Progressive Radio Network, Dr. Kelly Fishman joined the conversation to break it all down. From muscle health and recovery to the science behind Fortetropin®, this episode offers one of the most in-depth looks yet at how nutrition can support long-term mobility in pets.
Why Muscle Health Matters at Every Stage
Many dogs are naturally predisposed to physical challenges based on their breed and structure. From French Bulldogs to Labradors, different body types can put stress on joints and increase the risk of injury over time.
That’s where muscle comes in.
Strong, healthy muscle helps support joints, stabilize movement, and reduce wear and tear on the body. As Dr. Fishman explains, many of the issues we see later in life can be supported earlier by focusing on strength and conditioning—not just reactionary care.
By supporting muscle proactively, pet parents can help their dogs stay active, mobile, and more resilient as they age.
A New Approach to Supporting Muscle

One of the biggest challenges in veterinary medicine has been finding safe, effective ways to support muscle health in pets.
That’s what initially drew Dr. Fishman to MYOS.
She noted that it stood out as something entirely different—a food-based solution designed specifically to support muscle.
At the center of this approach is Fortetropin®, a natural ingredient derived from fertilized chicken egg yolk.
Supporting Muscle—Even During Recovery
Muscle health isn’t just about building strength—it’s also about maintaining it, especially during times when pets are less active.
Whether it’s due to aging, injury, or recovery after surgery, muscle loss can happen quickly. Dr. Fishman emphasized how important it is to support muscle during these periods.
“It supports not even growing muscle, but maintaining muscle during times of injury… if you’re on bed rest… it works to maintain that muscle.”
Taking a Whole-Body Approach
Dr. Fishman also highlighted the importance of looking at mobility from a bigger picture perspective.
Muscle and joint health go hand in hand, which is why combining muscle support with joint-supporting ingredients—like green-lipped mussel—can be especially beneficial.
This kind of holistic approach helps pets stay active, comfortable, and strong from multiple angles.
Helping Pets Live Stronger, Longer Lives
At the end of the day, muscle health isn’t just for athletic dogs—it’s essential for every pet.
By supporting muscle early and consistently, pet parents can help their dogs and cats maintain strength as they age, recover more effectively from injury, and stay active and mobile longer.
