Dog Supplements 2025: Functional Chews from Royal Canin & Vitail
Supplements Go Functional: Everyday Wellness Trends in 2025
Supplements aren’t just for senior dogs anymore. In 2025, functional supplements became one of the fastest-growing categories in pet care. Instead of pills and powders, brands are rolling out tasty chews designed to be part of a dog’s daily routine — much like a multivitamin for people. This shift marks a major evolution in how pet parents view wellness: not just about solving problems, but about proactive, preventive care for dogs of all ages.
From Medicine Cabinet to Daily Routine
Traditionally, supplements for dogs were used in very specific cases — glucosamine for arthritis, probiotics for diarrhea, fish oil for skin conditions. They were usually powders sprinkled on food or pills hidden in peanut butter, often reserved for older pets or those with health issues. But just as human wellness has embraced probiotics, collagen, adaptogens, and daily multivitamins, pet care is now catching up.
According to industry surveys, more than half of dog owners report giving their pet some form of supplement daily in 2025. What was once “optional” has become “expected.” And with dogs living longer, busier, and more urban lives, the demand for everyday wellness support has skyrocketed.
Royal Canin Biotics
Royal Canin launched its Biotics Powered Supplements line, including Digestive & Immune Health Chews, Digestive Chews, Joint Chews, and Skin & Coat Chews. Each formula targets a common pet parent concern while tying into Royal Canin’s existing nutrition expertise. By putting gut health front and center, this line shows how microbiome science is shaping pet wellness.
Microbiome research has been a growing field in veterinary science. A healthy gut can influence digestion, immunity, skin health, and even mood. By offering probiotic-based chews, Royal Canin is tapping into one of the strongest consumer trends in both human and pet wellness: “heal the gut, heal the body.”
Vitail Supplements
Vitail entered the market with four cold-pressed soft chews: Hip & Joint, Calming, Skin Health + Seasonal Allergy, and Gut Health. Their positioning is simple: proactive care for everyday dogs. This reflects a shift in how pet parents view supplements — not as something “extra,” but as part of a long-term health plan.
Cold-pressed chews are particularly appealing because they avoid high-heat processing, which can degrade sensitive nutrients like omega-3 fatty acids and probiotics. They’re also highly palatable, meaning compliance isn’t a battle. Dogs think they’re getting a treat — but really, they’re getting targeted nutrition in every bite.
Why Functional Supplements Matter
Supplements are moving from “problem solvers” to “preventive care.” Instead of waiting until arthritis sets in, pet parents are starting joint chews earlier to delay stiffness. Instead of only giving probiotics after antibiotics, they’re becoming a daily habit to support digestive balance.
Popular categories reflect modern lifestyle needs:
- Calming & Stress Support – Dogs in busy households or noisy urban settings may benefit from L-theanine, chamomile, or melatonin.
- Gut Health – Prebiotics, probiotics, and postbiotics can reduce sensitivities and improve digestion.
- Joint Care – Glucosamine, chondroitin, MSM, turmeric, and green-lipped mussel help protect mobility.
- Skin & Coat – Omega-3s, fish oil, and biotin support shiny coats and reduce inflammation.
Because these supplements come as soft chews, compliance is easier than ever. Dogs see them as treats, not medicine, which means fewer skipped doses and more consistent results.
What Pet Parents Should Watch
As with any growing category, not all supplements are created equal. Some products are backed by clinical studies, while others rely more on marketing than science. Pet parents should keep an eye out for:
- Ingredient transparency – Are all active and inactive ingredients clearly listed?
- Evidence-based claims – Is there veterinary or clinical research behind the formula?
- Third-party testing – Are products tested for purity, potency, and safety?
- Compatibility with diets and medications – Always check with a veterinarian before combining supplements with prescription foods or drugs.
Veterinary guidance is still key. A supplement may be safe for most dogs, but your individual pet’s age, weight, and health conditions should always be considered. For example, some calming supplements may interact with prescription sedatives, while certain joint supplements may not be appropriate for dogs with liver disease.
Spotlight on Ingredients
Functional supplements are only as good as the ingredients inside them. Here are some of the most common — and what science says about them:
- Glucosamine & Chondroitin – Proven to support cartilage health and reduce stiffness.
- Omega-3 Fatty Acids – Anti-inflammatory, great for skin, joints, and even heart health.
- Probiotics & Prebiotics – Support gut flora, improve stool quality, and boost immunity.
- L-Theanine – A calming amino acid found in green tea, helps reduce stress without sedation.
- Turmeric & Curcumin – Natural anti-inflammatories, sometimes paired with black pepper for better absorption.
- Mushrooms (Reishi, Lion’s Mane, Turkey Tail) – The “next wave” of adaptogens, being studied for immune and cognitive health.
Pet Parent Voices
It’s powerful to see pet parents share results that line up with what veterinary studies have found:
- A Labrador with early stiffness whose owner reported improved mobility after several weeks on joint chews — echoing clinical trials showing dogs treated with glucosamine + chondroitin had significant improvements in pain, weight-bearing, and clinical severity scores by day 70. (PubMed)
- A rescue terrier sensitive to storms whose signs of panting, hiding, pacing, and tremors lessened when using calming chews with L-theanine — parallel to an open-label trial where storm-sensitive dogs had reduced anxiety scores and returned to baseline more quickly after storms. (ResearchGate)
- A French Bulldog with digestion issues whose stool quality improved after starting a probiotic chew — reflecting randomized trials in shelter dogs where synbiotic supplementation significantly reduced diarrhea incidence compared to placebo. (PubMed)
These stories aren’t just anecdotes — they align with published research showing supplements can play a role in mobility, stress reduction, and digestive health.
🧪 Science Snapshot: Joint Health in Dogs
A randomized, double-blind, positive-controlled trial of 35 dogs with hip/elbow osteoarthritis found that dogs receiving glucosamine + chondroitin showed statistically significant improvements in pain, weight-bearing, and clinical scores by day 70. (PubMed)
A more recent placebo-controlled trial of 40 dogs tested a multi-ingredient supplement (glucosamine, chondroitin, Boswellia, hyaluronic acid) over 60 days, showing reduced pain and better mobility. (PLOS One)
🧪 Science Snapshot: Calming & Anxiety (L-theanine)
In an open-label prospective trial of 18 storm-sensitive dogs, L-theanine (Anxitane®) significantly reduced global anxiety scores (P < 0.0001) and shortened recovery time after storms (P = 0.0063). (ResearchGate)
Specific behaviors improved, including drooling (83 %), panting (76 %), hiding (78 %), and pacing (79 %).
🧪 Science Snapshot: Digestive Health & Probiotics
A double-blind, randomized, placebo-controlled trial of 773 shelter dogs showed those given a synbiotic supplement had fewer cases of diarrhea:
- Days with diarrhea: 2.0 % (synbiotic) vs. 3.2 % (placebo), P = 0.0022
- Dogs with diarrhea in first 14 days: 18.8 % vs. 27.2 %, P = 0.0008
- Dogs with ≥2 consecutive days of diarrhea: 4.6 % vs. 8.0 %, P = 0.03
The Future of Pet Supplements
The supplement space isn’t slowing down. Experts predict that the next frontier includes:
- Personalized Packs – Custom supplement blends delivered based on a dog’s DNA, lifestyle, or health profile.
- Adaptogens & Botanicals – Ingredients like ashwagandha, CBD (pending regulation), and mushroom extracts.
- Food-Supplement Hybrids – Kibble or fresh food already fortified with functional ingredients.
Just as human wellness trends have exploded, dogs are poised to benefit from a wave of innovation that blends science, convenience, and preventive care.
Final Thoughts
Functional supplements in 2025 are no longer niche. They represent a broader shift in how we care for dogs — moving from reactive solutions to everyday wellness strategies. Whether you’re considering gut health chews, calming formulas, or joint support, the key is to look for quality, research-backed products and to work with your veterinarian for the best results.
