How our chews work

Mighty Marrows are designed to be gradually gnawed and softened with saliva.

Saliva hydrates the collagen, creating a softer, flexible texture that moves around the teeth during chewing. This action helps provide mechanical cleaning, supporting the removal of food debris and plaque buildup.

Each chew is designed to be enjoyed over multiple supervised chewing sessions.

New to Mighty Marrows?
For your dog’s first few chew sessions, we recommend pre-softening by soaking one end in warm water for approximately 1 minute. This softens the outer layer, helps release more flavour, and gives your dog a gentler introduction while you get to know their chewing style.

You can continue pre-softening anytime your dog prefers a softer chew.

Ingredients

Mighty Marrows are made with limited, functional ingredients. Each chew is made from one protein source.

Beef Collagen: Beef Liver & Spirulina Beef.
Pork Collagen: Pork & Parsley, Bacon, Goat Milk & Peanut.
Premium Marine Collagen: Tilapia-sourced marine collagen with a salmon flavour profile.

Ingredients: gelatin, collagen, natural colour and flavours specific to each chew, and salt.

Our natural flavour and colour come from thoughtfully selected ingredients, including:

Spirulina: A nutrient-dense algae that supports fresh breath, healthy gums and overall oral wellness.

Parsley: A natural breath freshener with antioxidant and digestive benefits.

Black Carrot Extract: provides natural colour and antioxidants while supporting skin, coat and overall wellness.

Naturally Unique: Every Mighty Marrow is hand-poured in small batches using simple, functional ingredients. We prioritize ingredient quality over cosmetic perfection, so slight variations in colour, shape, texture, air bubbles or collagen foam are completely normal.

Sizing & Age Guide

Choosing the right chew depends on more than weight alone. Consider your dog’s size, mouth size, chewing style, age and dental history when selecting a chew.

Small: 4" × 1"
Best suited for dogs under approximately 14 lb.
50 g • 150 Calories per full chew

Large: 6" × 1.5"
Best suited for dogs over approximately 14 lb.
95 g • approximately 285 Calories per full chew

Jumbo: 8.5" × 1.5"
Designed for larger dogs over approximately 30 lb or more enthusiastic chewers.
166 g • approximately 500 Calories per full chew

For enthusiastic chewers, consider sizing up. A larger Mighty Marrow may help encourage slower, more gradual gnawing and extend chew time. If your dog attempts to aggressively crush, snap or bite through the chew, discontinue use.

Age Guidance

Mighty Marrows can be enjoyed by dogs at many ages and life stages, provided they have healthy teeth and the chew is appropriate for their size and chewing style. For puppies, senior dogs, or dogs with sensitive, damaged or compromised teeth, choose chews carefully and speak with your veterinarian if you’re unsure whether a firm chew is appropriate.

Care & Safety

• Always supervise your dog while chewing.
• Choose a size appropriate for your dog's weight, mouth size and chewing style.
• When the remaining piece becomes small enough to be swallowed whole, remove it from your dog.Don’t toss it! Save the end to make a collagen puff!
• Start with approximately 30-minute chewing sessions. Mighty Marrows are high-protein chews designed to be enjoyed over multiple sessions.
• Remove the chew before it becomes overly soft or gummy.
• Allow it to air-dry completely between sessions.
• Store in a cool, dry place.
• Not every chew is for every dog.

Care Tip

As collagen softens, a small amount of residue may transfer to your dog’s chin, paws or nearby surfaces. Chew holders or a designated blanket can help keep cleanup simple. Wipe any fresh residue away with a warm, damp cloth.
