Many reasons for me, most of all(reason I will cull a cur dog as well) is too much bottom... properties dictate what type of dogs a person can run.. smaller properties necessitate short range, hard stopping, silent dogs... plain and simple.
Whenever yall get a dog with too much bottom and you want to cull him, before you do you need to email me before you do that and send them my way. You to TexasLacy them dogs are my favorite.
