Hi, okay where to start? I have 2 EB puppies, they are 9 months old now , and are brother and sister. I got my pups when they were 10 months old , both were biting us all the time in the beginning. I also have 6 kids in my family that are under the age of 5, one is my Grandson, and they are all cousins. I had to find a way to curb them from biting us, but especially the kids. What I did was I made sure I handled the puppies ears, I put the outside part of my hand in their mouth, gave them food, and took food away from them as well as their treats and toys, so they would be used to this if the kids should do any of these things to them. I also taught my Grandson , who is 5 and is here about 45 hours a week, to be gentle with the pups, to pet them nice, not tease them, or pull them. I taught him that animals have feelings too, and if you pull ears or tails , they feel the same pain as people do when their hair gets pulled. I also taught him not to bug them when they were eating, and to always use an open hand when giving a treat to them. If your hand is flat and open, it is impossible for them to bite your hand. The other thing we did when the pups would bite us, or our toes, or pants, etc, is we would either grab the soft skin on the back of their neck and pull back and in a firm voice say NO, or ouch, the other thing that worked is to place your thumb in their mouth and lay it across the tongue and hold it with the chin in your hand, they can't bite when you do this. We only had to do this for a few weeks, and they stopped biting us . Good luck and I hope you find a technique that works for you.
