Frequently asked questions
How is Hip & Joint Dog PLUS different from Hip & Joint Dog?
Both contain glucosamine, chondroitin, MSM and hyaluronic acid at the same levels. PLUS has serrapeptase, a natural enzyme, added. It isn't a stronger dose: it's the same formula with one extra ingredient.
How soon will I notice a difference?
Every dog is different, but many owners tell us they see a change in their dog's movement after around three weeks of daily use. Give it at least a month before judging.
How long does a pouch last?
It depends on your dog's weight. A 200g pouch lasts a medium dog (15–40kg) 31 days, a small dog (up to 15kg) 44 days and a large dog (40kg+) 15 days. The full feeding table is above.
Is it suitable for competition and working dogs?
Yes. None of the ingredients are banned by the GBGB, IGB, ISDS, British Flyball Association, IFSS, the Kennel Club, UK Agility or BASC. Full details are below.
My dog is a fussy eater. Will they eat it?
It's a fine powder that mixes into your dog's usual food, and lots of our reviews mention dogs happily eating it. If your dog is wary of anything new, start with a smaller amount and build up over a few days.
Can I give it alongside medication?
If your dog takes medication, is injured or has an ongoing health condition, please check with your vet before using this supplement.
Can I claim for it on pet insurance?
Some of our customers have successfully claimed for this supplement through Petplan. Check your own policy, as cover varies.
