I don't currently have a dog, but I often enjoy working with my uncle's dog when we are together. Della is a two year old chocolate lab. She is a true working dog. She is not house-broken and is basically ignored by my uncle's family. He takes her for a 5 mile run every morning and uses her for companionship when he's working in the woods and also for duck hunting. She retrieves very well (well, not as "soft" as she should be) and is an excellent swimmer. However, she has many issues that my uncle has thus far failed to address. Basically, she acts like a puppy because she's never been properly trained what is not acceptable. For example, at the cottage Della is kept outside on a long lead. When she sees you approaching she will crouch down and wag her tail. As soon as you are about 6 feet away, she starts barking and lunging. She will lunge at you and snap at your arms and hands or anything you are carrying. She knows sit, stay, come, fetch, kennel, heel, and load (get in the car), but she doesn't listen when you are approaching her. Basically, to get her collar and lead on you have to wrestle her and are lucky if you come out without any hard snaps or nips. She also lunches and snaps at her "duck" buoy if you are holding it, instead of properly waiting for you to tell her what to do.
My sis and I would like to try rewarding her when she does the commands she knows, but Della has never had a treat in her life and we don't know how to introduce this without her going absolutely crazy. I fear that she will figure out I have treats in my pocket and then keep right on lunging and snapping at my pockets and hands. She just doesn't listen, and she's so big and strong it's very tiresome trying to get her to do the simplest of things. If she gets away from you, she just runs everywhere and will actually charge people and lunge at them. When she gets in this state, it's basically impossible to get her to focus. Once she is on her lead walking, she does good (she knows "heel" pretty well now, thanks to one of those prong collars my uncle uses) and once she has started her routine of waiting for the "duck" to be thrown and then being told to fetch, she is great. It's the things like getting her on her collar and then getting her back off onto her yard lead that she won't do. Most of our relatives are afraid of her and won't go near her b/c of the lunging.
I really think this is my uncle's fault since he is a very high strung person and the dog just feeds off of his personality. He's not mean at all and she listens to him ten times better than I, but instead of rewarding her, he's always shouting "DELLA COME, DELLA OFF!, DELLA NO!!!!" and she just gets more hyper. I don't think she really knows what he wants.
