My 6 month old Patter-Jack had started to hold his back leg bent and off the floor. He wasn’t showing any signs of pain and was his usual boisterous, energetic self. I was advised after speaking to a Patterdale breeder that it was possibly due to him being over active before 4 months old, and that he’d probably stretched his ligament but it should rectify itself without intervention from a vet. Wanting to aid his joint care, but unsure which supplement to chose out of multiples advertised I chose PDSA joint supplements as I figured they’d be closest to what his vet would have supplied. Really pleased I chose them, he’s been taking them for 2 1/2 weeks and there’s a noticeable improvement in his leg. Added bonus is it’s not cost me an arm and leg to help him. So impressed with them I sent for the bigger box a week later to make sure we had a good supply👍🏻.
