What Are the Best Supplements for Dogs in the UK?

Short answer: The best dog supplements in the UK support specific health areas — such as joints, digestion, skin & coat, anxiety, and overall immunity — and come from trusted brands that use vet-approved ingredients, are easy to give (like soft chews), and are tailored to your dog’s life stage and size.

When it comes to keeping our dogs healthy, most of us focus on food, exercise, and love — and rightly so. But in recent years, more and more UK pet parents have started asking an important question:

“Should I be giving my dog supplements?”

The answer? In many cases, yes — especially when they target specific issues like joints, digestion, or anxiety.

In this article, we’ll walk you through why supplements can help (even with commercial dog food), what makes a good dog supplement and some of the most trusted options available in the UK.

Why Give Your Dog Supplements?

Even if your dog eats a high-quality, complete food, supplements can:

  • Fill nutritional gaps caused by processing or poor absorption
  • Support specific issues like joint pain or digestive trouble
  • Help older dogs stay active for longer
  • Boost immune function and skin/coat health

Think of them like a targeted boost — not a replacement for food, but a way to optimize your dog’s health based on their age, breed, or challenges.

What to Look For in a Good Dog Supplement

Here are a few signs you’re buying a high-quality product:

  • Made specifically for dogs
  • Backed by veterinary science or formulated by vets
  • Contains clearly listed, functional ingredients (e.g., 400mg glucosamine)
  • Free from artificial flavors, colors, or unnecessary fillers
  • Easy to give — ideally in soft chew, liquid, or powder form
  • Positive reviews from other dog owners

Avoid anything with vague claims, hidden ingredients, or “one-size-fits-all” pills with no dosing guide.
