If one of the dogs caught 105 rabbits, I'd say yes, that is pushing it a bit.
I don't care who disagrees with me or whatever, but seeing as I am not a keeper, pest controller, professional hunter or someone that needs to 'test' their young dogs to the limit for whatever reason, I find all this 'numbers' crap very disheartening, and am not surprised that there are so many potentially good young dogs being ruined every f**cking year!
