How are Marleybones' meals made?

We only use high quality, freshly prepared ingredients, which are sealed raw in their aseptic packaging and slow-cooked, reaching temperatures of over 100°c for just a few minutes. This method not only locks in essential nutrients, moisture and natural flavours, but also keeps our meals as fresh as possible without the need for preservatives or freezing. Marleybones is the easiest way to feed healthy!

Is Marleybones suitable for puppies?

All our meals have been specially formulated for all life stages, taking the issue out of having to switch your dog's food as they grow. Our quiz algorithm adjusts so that puppies between the ages of 2-12 months receive extra nutrition to ensure they grow strong and healthy!

Do I need to freeze the food?

One of the benefits of Marleybones meals, is that you don't need to clear your freezer of ice-cream and just need to store them in a cool, dry place. As a bonus, they take up much less space than traditional food, and they're easy to stack and store. At Marleybones, we are proud to offer pantry fresh meals that remain fresh for up to 18 months when stored in a cupboard. Unlike other products that use preservatives, additives, or other undesirable ingredients that compromise the nutritional balance of the food, our innovative packaging and cooking methods help us achieve a shelf-stable product without sacrificing quality.

Can I easily stop my subscription?

Marleybones subscription service is easy to manage. You can both push your delivery date or stop your subscription altogether. You're of course welcome back anytime.

What makes feeding a Pyrenean Mastiff so unique?

The Pyrenean Mastiff's giant size, steady temperament, and unique growth pattern require a carefully balanced diet focused on joint health, controlled growth, and easy digestion.

This breed is known for a gentle nature and impressive frame, but their large bones and rapid early growth mean nutrition needs close attention. Compared with smaller dogs, Mastiffs typically have a slower metabolism and are more prone to joint issues and bloat if their diet isn't tailored to their needs.

These calm companions don't need a high‑energy formula. A moderate‑calorie, balanced approach helps prevent excess weight while supporting the muscle mass they require. A precise calcium-to-phosphorus balance - roughly 1.2:1 to 1.6:1 - is essential to ensure bones develop strong and steady.

Feeding a Pyrenean Mastiff is less about giving more and more about giving what's right: nutrients that support muscle, bone and joints, delivered in a way that keeps digestion calm and consistent.

What nutritional factors matter most for giant breeds like the Pyrenean Mastiff?

Giant breeds need high-quality protein, balanced minerals, joint‑supporting nutrients, gut‑friendly fibre, and portion control to thrive.

Aiming for around 23–30% protein from real, responsibly sourced meat or fish provides the amino acids necessary for lean muscle growth and maintenance. Joint support is key: Omega‑3 fatty acids (often from oily fish), together with glucosamine and chondroitin, help maintain cartilage and mobility as dogs age.

Balanced minerals — especially calcium and phosphorus — promote healthy skeletal development without encouraging overly fast growth. For digestive comfort, prebiotic fibres such as chicory root and yucca support a stable gut environment, reducing tummy upsets and aiding nutrient absorption.

How does Marleybones' Pantry Fresh® approach support giant breeds?

Marleybones Pantry Fresh® meals are slow-cooked, nutrient-rich, and portioned to support the steady, healthy development of giant breeds like the Pyrenean Mastiff through every life stage.

How can owners feed and care for their Pyrenean Mastiff's dietary needs?

Feed two measured meals daily, rotate lean proteins, use raised bowls, and encourage slow eating — plus schedule regular vet check‑ups for lifelong wellbeing.

For adult and senior Mastiffs, two balanced meals a day provide steady energy without overfilling their large stomachs. Rotating proteins — for example, fresh chicken, beef and salmon — offers a broader range of amino acids and keeps mealtime interesting.

Raised bowls, positioned at shoulder height, reduce the amount of air swallowed and can help lower the risk of bloat. Encourage slower eating with puzzle feeders, slow‑feed mats, or by spreading meals out to discourage gulping.

Keep a close eye on body condition: there should be a visible waist and ribs that can be felt beneath a thin layer of fat. Regular vet checks help monitor muscle tone, joint health, and portion accuracy as your dog matures.

Watch for rapid changes in weight

What feeding questions do Pyrenean Mastiff owners often ask?

Owners often ask about transitioning to fresh food, managing growth safely, supporting joints, choosing all‑life‑stage recipes, and promoting digestive balance.

Transitioning to a fresh diet like Marleybones Pantry Fresh® works best over 7–10 days, gradually blending increasing amounts of the new food with the old to prevent digestive upset. Warning signs of overly rapid growth — such as awkward movement, quick weight gain or loss of waistline — are cues to reassess portion sizes and mineral balance.

Joint health benefits from Omega‑3s, glucosamine and chondroitin, along with the right calcium:phosphorus ratio — all elements found in Marleybones recipes. Because Pantry Fresh® meals are formulated for all life stages, a single recipe can often meet your Mastiff's needs from puppyhood through senior years. For sensitive tummies, supplements like the Marleybones Gut Health Supplement — rich in natural prebiotics — can further support digestive wellbeing.
