Hey all! I'm new here too. I been reading these post I do have a concern, I have a 10 month black lab name Gracie and she LOVES to play fetch and drops the ball right a my feet every time and she could go all day...NO JOKE!! I usually go 20 / 30 min maybe 5 days a week. I the question I have is....that too long and hard for a my young Gracie? thanks for inputs!
