No matter what we do with our dogs, they learn from it. Don’t offer your puppy your body parts as toys. Offer toys that he can chew and toys that he can tug at without worry about injury to either him or you.
Training a dog isn't something you do and are done with. Training a dog lasts for as long as you keep it up and are consistent in the results you expect. It takes constant reinforcement and repetition. You train your dog to sit and every time you give the command and he does, you are training. What is most important is that you continue to reward your dog whether you use an "atta boy", a treat, or a pat.
Some people call them "Bark Collars" but, barking collars don't bark and aren't only used to stop dogs from barking. They are shock collars. Their sole purpose is not to train but to punish undesirable behavior with pain.
Punishment, either mental or physical beats up a person or brings them down. Discipline teaches self control. Parents weren't meant to bully their children with punishment. We are meant to teach our children to learn social norms and control themselves within those norms.
When my children were young, I learned that sometimes you literally have to have a fire lit under you to appreciate how dear those close to you are. We moved to the country looking for a safer, less stressful life for ourselves and our two young children. Our rural Minnesota house sat well back from the road. There was ample room for Nicki, our three-year old, and Lance, our six year old, to play safely on the five acre plot of land that surrounded our house.
We all want to provide for our children, to give them a better life than we had, no matter how rich or poor a background we come from. Yet, I think the best way to provide for our children is to prepare them to lead a rewarding life.
