@Aria20 I have no idea, she told me 15 mins includes play at home, thats so difficult to monitor as obv he plays with our other dog. We have been driving to the park and letting him have 15 minutes of play at his own pace, he's not that hectic so it seems fine.
I am going to research further as I was told previously 2 x 15 (but then obv other pup is small breed). I am not even sure she was a vet now, I have a few concerns as paid loads for a best start package and think she was an assistant. She couldn't confidently answer my questions, especially about his limp (which has now gone) which worries me.
