I ran out of proflax Bounce, which I have been using on my Lab for 2 years now, she’s 10 years old and still really active, still walks between 1 and 2 hours a day. It was 5 days before I was heading back to the specialist pet food store to grab some food as well. After 5 days without Bounce she was lame due to Arthritis, now back on Bounce after a few days she was back to normal, as she’s got a condition I give it with breakfast and dinner.
