When I go out to get them, Belle comes right to me on command (she just picked this up in the last couple weeks finally )

Maggie is completely absorbed in chewing on the chain link of their dog pen and baying (SOOO loud!) that she either doesn't hear me or it doesn't register with her that I'm calling her. She is responsive to her name in the house, but outside is a totally different story. I call her name, and tell her to come...she ignores me...I call her name, wave a treat right in front of her nose...she ignores me...I reach out to grab her collar while I am close enough to wave the treat...she runs to the water bucket, tips it upside down, puts her muzzle in it and makes an echo as she continues to bay...oh, and keeps ignoring me...I wave the treat at her and call her as she runs back to the fence to keep on chewing/baying and she will sometimes try to take the treat (if I'm quick I can get her leashed at this point, but if not, she will sit long enough to act like she might be good, get the treat, and slip through my grasp yet again). I try to leash her before she gets the treat, but she is sooo wiggly and has all that loose skin, it's like trying to catch a 50 pound water snake (you know, those ones you can get in museum gift shops and science stores?) and it takes both hands to get the collar and leash connected to one another. I want her to learn that coming when called is what earns her rewards, and worked with her yesterday for about 20 or 30 minutes just on recall in the pen. She did it a few times, but is very slow to catch on . I have worked with her for quite a while in 5-10 minute sessions, but yesterday's session was the longest we've ever worked on this.
