Dogs? Some day, yeah, I'd like to breed. Collies are what I want to breed so far, but there is a chance that some day when I get my Koolie, I will decided I'd rather breed koolies. But any time soon? Uh, no. Logan's breeder is free to use him is she wanted to, but I can't per contract - and I don't have any plans/wouldn't want to, anyway.
I see this happening maybe 15ish years down the road. Possibly sooner, depending on how things pan out, but certainly not in the immediate future and not with any of the dogs I have now.
I would want to breed for what I find to be ideal in my chosen breed. I'm still working out what that might be in collies (I looooove Logan's lines. Like, a lot.), but if I end up with koolies, I don't even have a starting idea yet, other than health tested.
Crested geckos? **** yes. I want to get a nice girlgecko to breed with Jagrafess some day when I can afford one. I got lucky with his structure for a $50 gecko, it's actually really good - not just his head, but overall, he's just nicely put together. I don't know how genetics factors into gecko temperaments, but he has a very nice temperament, too.
