When Your Dog Starts Telling You Something's Wrong

Stiff joints. Slower mornings. Hesitation on the stairs they used to fly up. Dogs can't tell you when something hurts — but they show you.

Joint health can decline faster than most owners expect. The right support, started early and given consistently, makes a real difference to how your dog moves, feels, and ages.

We Show Our Work

Most supplement brands hide behind vague claims and borrowed credibility. Dr. Ferg's was built on the opposite principle.

Every ingredient has a name, an origin, and a reason to be there. New Zealand grass-fed. Sustainably farmed. Traceable from paddock to bowl. No fillers. No shortcuts. No claims we can't back up.

Because your dog doesn't know what's in the bottle. But you should.

Our Ingredients

A Vet in Your Corner

Dr. Ferg's was founded by Dr. Feargus McConnell — a veterinarian licensed in New Zealand and Colorado — after years of recommending supplements he wasn't fully satisfied with.

His own dog Ace, a retired racing greyhound whose body was pushed hard by the track, needed better support than what was on the shelf. So Dr. Feargus made it himself — traceable, honest, and held to a standard he'd put his name on.

Because he did. It's right there on the label.
