Cold-weather adventures are magical — snow-covered trails, frosty air, and a dog who can’t stop wagging their tail at the first sign of winter.
But winter hiking places unique demands on a dog’s body.
They burn more calories, need more joint support, and often require nutritional adjustments to stay healthy and energized through colder months.

Here’s what really matters for winter trail nutrition — and what every dog owner should know.

1️⃣ Extra Calories for Extra Energy

Dogs burn more calories in winter because they’re:

• Staying warm
• Moving through snow
• Exerting more effort on uneven terrain

According to PetMD, dogs may need up to 10–20% more calories in cold weather depending on activity level and coat type (PetMD – Feeding Dogs in Winter).

How to apply this:

• Bring high-value snacks for long hikes
• Increase meal portions slightly on heavy activity days
• Avoid “carb bombs” — prioritize protein and healthy fats

💡 Trail Tip:
If your dog loses weight during winter hiking season, adjust calories immediately. Weight loss = energy deficit.

2️⃣ Omega-3 Fatty Acids: Winter’s MVP Supplement 🐟

Omega-3s support:

• Joint lubrication
• Anti-inflammatory response
• Skin and coat health (important in dry winter air)
• Cognitive function

Vet nutritionists widely recommend omega-3 supplementation for active or older dogs.
The AKC Canine Health Foundation notes that omega-3s (EPA & DHA) reduce inflammation and support long-term mobility (AKC CHF).

Good sources:

• Salmon oil
• Krill oil
• Algae-based omega-3 (great for sensitive stomachs)

💡 Start with small doses — too much too soon can upset the stomach.

3️⃣ Vitamin D — Yes, Dogs Need It Too ☀️

Winter = less sunlight.
Less sunlight = lower natural Vitamin D synthesis.

According to a study in the Journal of Veterinary Internal Medicine, dogs often have lower vitamin D levels in winter, and adequate D supports:

• Strong bones

• Immune system health

• Muscle function

• Overall energy levels

Most dogs get Vitamin D from food, not sunlight — but winter activity can increase the demand.

What to do:

• Choose a high-quality complete food with balanced vitamin D
• Ask your vet before giving standalone D supplements (too much can be toxic)

💡 Avoid DIY supplementation — vitamin D must be dosed carefully.

4️⃣ Joint Support: Winter Stress on Active Dogs

Cold weather stiffens joints, tightens muscles, and makes old injuries flare up.
Winter terrain adds stress from:

• Ice
• Slippery ground
• Deep snow
• Higher impact on landing

Canine Arthritis Management (CAM) warns that cold temperatures can worsen early-stage joint issues (CAM – Winter Tips).

Helpful supplements:

• Glucosamine
• Chondroitin
• MSM
• Green-lipped mussel
• Turmeric/curcumin (vet-approved doses)
• Collagen peptides

💡 Pro Tip:
Start joint support early — before symptoms appear — especially for large breeds or active trail dogs.

5️⃣ Hydration Still Matters (Even When It’s Freezing!) 💧

Dogs lose moisture through:

• Panting
• Cold, dry air
• Increased exertion

Winter dehydration is very real and often overlooked.

PetMD states that dogs may drink less in winter while actually needing more hydration due to cold-weather exertion (PetMD Winter Hydration).

What to do:

• Bring water — always
• Offer frequent, small sips
• Don’t rely on snow (it lowers body temperature and contains impurities)

6️⃣ Electrolytes, Broth & Warm Snacks

For long winter hikes, consider:

• Bone broth (hydration + electrolytes + warmth)
• High-moisture treats (soft meat snacks)
• Warm water added to kibble

Warm calories = easier digestion + more comfort.

Great for picky eaters or dogs who lose interest in cold weather.

7️⃣ What’s Just Marketing? 🚫

⚠️ “Winter superfood bars for dogs”
→ Often overpriced versions of normal treats.

⚠️ Gimmick supplements with no scientific backing
→ Always check for third-party testing.

⚠️ Overpromised multivitamins
→ Most complete dog foods already contain balanced micronutrients.

What matters:
Protein, omega-3s, hydration, joint support — not hype.

❤️ Final Thoughts

Winter hiking feeds the soul — but it also demands more from your dog’s body.
With the right nutrition plan, you can keep your trail buddy warm, energized, and healthy through every snowy adventure.

Remember:
❄️ More calories for energy
🐟 Omega-3s for joints & coat
☀️ Balanced vitamin D
🦴 Joint support
💧 Hydration, always

A well-fueled dog is a happy dog — and a happy dog makes winter trails unforgettable.
