Why it matters
80%Joint changes build quietly with age, and bigger or more active dogs feel them sooner. Daily support works best when you start early, before the stiffness shows.

Limping is the obvious sign, and usually the last one. The first changes are quieter, and easy to put down to age.
They still get on the couch or into the car, but think about it first. That pause wasn't there last year.
The first few steps after resting look stiff, then they loosen up. That's why it's so easy to miss.
The usual route takes longer. More stops, or turning for home earlier than before.
They used to bound up. Now they take them carefully, or wait at the bottom.
Still happy when the leash comes out, just less bouncy. Easy to blame on age.
A big hike used to cost them nothing. Now the next day is noticeably quieter.
The joint support gap
Regular dog food has little to no glucosamine, and many supplements stop at a partial serving. Two Rewoof chews give a medium dog 1,000 mg of glucosamine a day, plus MSM, chondroitin and green-lipped mussel.

Common questions
Each jar has 60 chews. Up to 25 lbs: 1 chew a day, so a jar lasts about 2 months. 25–75 lbs: 2 chews a day, about 1 month. Over 75 lbs: 3 chews a day, about 3 weeks. If you give more than 1 chew, split them between morning and evening.
Many owners notice smoother get-ups within 3–6 weeks of daily use. Joint support builds with consistency, so give it a full 8 weeks. Every dog is different.
Most dogs take it like a treat: it's a soft, duck-flavored chew. For very picky eaters, break it up over their food.
Yes, it contains green-lipped mussel, which is a shellfish. If your dog has food allergies, check the full ingredient list in Supplement facts above, or ask your vet.
Rewoof is a daily supplement, not a medicine. If your dog is on medication, is pregnant or nursing, is under 1 year old or has a health condition, check with your vet first.
