My girlfriend of five months has had two rescue Labs, one yellow and one chocolate, for 10 months now, both neutered. The yellow is about two years of age and is well behaved. The chocolate is 14 months and has no discipline whatsoever.
It has gotten to the point where the chocolate must be the center of attention at all times. He will push the other dog out of the way for pets, will not sit for treats, chews furniture, forces his way on to the bed after being told "no" multiple times. I believe the yellow is getting tired of the younger dog as well.
He is very protective of my girlfriend and will lay on top of her in the bed. I see this as more a sign of dominance than protection. He is not receptive to her commands unless there is a treat in hand.
There are several times where I have raised my voice considerably at the dog and he just becomes confused and less obedient out of fear. I hate to anthropomorphize the feelings of animals, but I am convinced he sees me as a threat for his mother's attention.
Unfortunately, the dogs only get about 30-60 minutes of leash exercise a day. They are outside in a small suburban yard for most of the days and there are minimal signs of digging and trying to escape.
What steps do I, my girlfriend, or us together need to take to allow the chocolate lab to be a more enjoyable aspect of our lives?
Thank you in advance
