Shortly after adopting our senior Bichon-mix we noticed that Lucy was in pain after a walk. We got a little scared and ended up taking her to an emergency vet and it turned out that Lucy had sprained or pulled a muscle in her back. At the time, we did not have any supplements in her daily routine, but the vet at the emergency clinic recommended this Nutramax brand of supplements. After laying low for a while (no jumping!) and adding these supplements to Lucy's regimen, we were able to see improvements relatively quickly. Lucy hasn't had any issues with pain anymore and she's able to still act like a puppy, even at 13. Overall, I would recommend these supplements for your dog, whether young or old, as it seems to work and was highly recommended by my vet.
