Hello, just some food for thought....
I got my Bredli girl from Casey Cannon and he actually keeps his fairly small. I don't know that he selectively breeds for smaller animals though.
His breeder males are only 5.5-6 feet and 800 grams or so. That actually surprised me when he told me. Obviously knowing that doesn't guarantee anything. We also discussed diet and he said he always slows them down at 2.5 years and they maintain a healthy body structure. He prefers lean and mean for a longer, healthier life.
I didn't get into size of his breeder females, but the dam that produced Fernie was a bit over 6'.
Just figured I'd throw that out there. But obviously you know what you'd be getting into regardless. I'm just Bredli crazy right now, hahhahahaha.
