This is Marley my 3 y/o Irish Wolfhound X American Bulldog. 8 weeks ago Marley severely tore his left Cruciate Ligament requiring immediate Surgery. K9 JF was recommended for him by a good friend who had had amazing results so I thought I would give it ago to help his recovery. Before I ordered the k9JF and less than 2 weeks after his first Surgery Marley had done the other Cruciate on his right leg. Wanting to buy him some time before more costly surgery I started him on the k9JF and K9 Mud. X-rays confirmed both Arthritis and a torn right Cruciate. Vet recommended immediate surgery once again but I decided to see if the k9JF & K9 Mud would make a difference and all I can say is WOW and Thank you so much for these amazing products. Marley is now out of his cage, he had been in for several weeks and back in his yard. I am hoping his progress will keep improving and have just ordered another 2 tubs of K9JF. Fingers Crossed we may just avoid further surgery. Thanks Steve and all at TuffRock for helping Marley regain his quality of Life!
