I have heard that the first three years of life with a lab are very trying, that there is a lack of focus in the dog that is exasperating, to say the least. Then they grow up and become the best dog you ever knew.
I have never owned a lab. I have had an Irish Setter, a Border Collie mix, a Shepherd/Husky mix, and this Jindo. They have all been super dogs, and blessings as companions. Their personalities were/are all different. The only constant is me.
Consistency and repetition will be your dog's saving grace. It takes a mountain of work on your part. Every minute that you spend with your dog, whether you are trying to or not, you are teaching your dog
something. You are either teaching him that you are something to be ignored, or you are teaching him that you are to be heeded.
Here is my three-year-old Jindo, Spirit, on the line this past May. I told her "Sit" as I got to the line. Watch her look at me, as she starts to sit, and decide that it isn't necessary, as I have my back to her and am preoccupied with these sticks.
The camera has a short video time, so I ignored her and shot. She knows that if I catch sight of her moving forward of the line while I shoot, that I will be on her like white on rice. A squirrel bumbling out of the woods might make her forget that, though, and you would have been treated to a glimpse of her blinding speed.
:D
She had a rough first year, used as a guard dog and treated none too gently. She broke loose of that place, went walkabout, and the county picked her up. She was seriously underweight when I adopted her, and had a raw spot on the front of her neck, as though she had been fighting a tether.
The nature of this breed (every Jindo believes it is born Alpha) and her former treatment (she flinches and goes defensive easily) requires a gentle, but firm hand. She knows that I love her to pieces, and have her well-being at heart, which gives my commands credibility. I (usually...) back them up with no fooling around, so she knows I mean them.
Her training with me has been based on setting her up to succeed, and giving her tons of positive feedback when she does. Wrongdoings are disciplined much like a parental dog would do, briefly, with growly voice, muzzle clamp, shaking the scruff of her neck or placing her on her back and talking mean. Her nature, and her rough treatment before I got her, though, make her likely to go into "survival" mode and she will be ready to defend herself should she believe herself to be truly threatened. I count on her love for me to lead her to submit to my guidance and symbolic correction.
I have heard it said that dogs have the mental capabilities of a three-year-old child. I treat these dogs like young children, which probably grates on the nerves of some, but I have been rewarded with dogs of amazing loyalty and obedience, true friends and members of my family.
