The Havanese sometimes play in a fashion where they look like they are baring their teeth and they are but it is all in fun. You have to figure out the difference between the fun and games and bite inhibition of puppies. It's an essential learning process that helps them with socialization.
When a puppy is just getting around, it's mom will correct her pup in various ways if it bites too hard. I remember once seeing Kat's head disappear in Risa's mouth as she had enough. She was a very tolerant mom with him but he was a step over the line boy that loved to egg her on. She did what any good mom would do and say - enough. He didn't learn the first time but he did eventually get it or maybe he actually resigned himself to 'get' it.
When you acquire a pup, the canine mom has done a significant amount of training on what will be tolerated in this new world and what won't and so do the humans. This continues after you obtain your little one letting them know the boundaries - the rules by sometimes overemphasizing the reaction. Such as playing too hard, the human would yell louder than necessary to say - ouch or what have you. You can even turn your back and stop play. This is a clear sign that enough is enough. They do learn from this at all ages. Puppies enjoy and need rules, boundaries and some would say - then your love but as a mother of 7 kids, I rather feel rules and boundaries and saying 'no' when they look at you to melt your heart is love too.
When they are doing the right thing, that's when the snuggles and hugs and kisses should come.
You never use negative training but a 'no' and stopping the play is part of development.
If you watch a dam with her puppies, you may think she is too rough but in reality she is quite gentle but direct and straight to the point. She doesn't want to say - joey sit - joey sit - come on joey sit. If a dam was to teach her pup to sit and they don't do that but if they were - they would say it one time and then if they didn't, she would put them into position then give them a signal of what a good boy you are even though she put him into position. As humans we have to follow suit. We say it one time, we place them into position or stop the play and then start again and praise when they do it right.
The first couple of years they are like sponges soaking it up. They can and do continue to learn later on but there's nothing like those first couple of years.
As you can see, Abigail has her teeth bared playing with Fiona. If either was to get too rough, a yelp would be let out and the other would learn that they went too far. If they don't learn, the receiver of such overtures would not play with them till they did 'get' it.
It's our job to foster that development and understand it and not hinder it as they are learning but give them rules and boundaries. They will love you even more for it.
It's rare for a dog to be balanced that lives without rules and boundaries. They are what we put into them.
We are off to shows this entire weekend and not back till Tuesday but we will be posting - investing our time with the dogs and the computer will come 2nd. I won't miss a day but realize our focus is the dogs.
More later...
