Best Pet Supplements 2025 — Omega-3, Joint Health & Probiotics
📅 July 2025 · Estimated read: 6 minutes
Both our Border Collie and Maine Coon take daily supplements — and the difference is noticeable. Our Border Collie's coat is glossier, her joints seem more comfortable after long runs, and our Maine Coon's dander has reduced dramatically. Here are the supplements that earned a permanent spot in our pet care routine.
Nordic Naturals Omega-3 Pet Soft Gels
Nordic Naturals is the gold standard for fish oil supplements — for humans and pets. Their pet formula is made from wild-caught fish and is third-party tested for purity (no heavy metals or toxins). It supports joint health, skin and coat condition, heart health, and brain function. Our Border Collie's coat has never been glossier since starting these. Our Maine Coon's dander reduced noticeably within a month.
Cosequin Joint Health Supplement for Dogs
Cosequin is the #1 vet-recommended joint supplement brand. It contains glucosamine and chondroitin to support cartilage health and joint function. Our active Border Collie runs 10+ km daily, and these help keep her joints comfortable. Available in chewable tablets that dogs think are treats. Start early — joint supplements are most effective as preventative care.
Purina Pro Plan FortiFlora Probiotic
FortiFlora is a probiotic supplement that's specifically formulated for dogs and cats. It helps maintain healthy digestion, especially during stress, dietary changes, or after antibiotics. It comes in single-serving packets that you sprinkle over food. Both our pets love the taste. Great for dogs and cats with sensitive stomachs or irregular digestion.
💊 Supplement Quick Guide
- Omega-3 (Fish Oil): Best for coat health, joint support, and brain function. Use for all pets.
- Glucosamine/Chondroitin: Essential for active dogs, senior pets, and breeds prone to hip/joint issues.
- Probiotics: Great for pets with sensitive stomachs, after antibiotics, or during stress.
