I see you read about my thoughts on grit and aggressiveness on my website. My Gunner dog actually sits on stand and doesn't move until told to. He also is trained to come back on command, regardless of how heated of a race he is in. I have full control over him and it works great for me.
I am currently training a Jagd/Cur cross, named Dixie. She's a young dog that has too much aggression on coyotes and has actually run off 5 different coyotes on stand. I'd much rather have a dog that is too aggressive and needs trained to the collar, than one that has no aggression and has to be pushed to get out from under one's feet. She is currently going through collar training to be more controllable. That's the key, in my opinion. From there, they will get the idea of the cat and mouse game and only get better stand after stand.
My breed selection for this litter was to produce a dog that will get the job done, when a coyote is bayed up. I hunt with alot of clients and some (including myself) just don't care to see an injured coyote suffering. This cross should produce dogs that will put an injured coyote down on the ground, allowing one to continue calling the stand for more incoming coyotes.
