I need your help, please, sweetie.
I have a friend - no, I really do, honestly - and she has a 9 month old GSD who is lovely, just quite bouncy and full of fun as they are at that age. She is a knowledgeable owner and has trained him quite extensively.
I am trying to persuade her that joining me and my pup on a pre-agility or flyball course would be a good idea (her pup loves balls) but she is a bit worried that he is too hyper and will steal other dog's balls etc. She also thinks it will be best to wait until he's been castrated, saying he'll be calmer then. I've tried arguing that castration won't calm him down, that he'll love the flyball etc but she's reluctant.
What do you think, oh venerable one?
TIA
