Hi, this my first post. I am not only new to beagles, but very new to owning Dogs.. For must of my life I have been a cat person, but that has changed. My beagle Linus is 11 weeks old and we've had him for 3 weeks now. I love my new dog, but it seems at times he plays rather rough and uses his teeth. I've read a few things on the web on how to deal with this, but like most info on dogs on the internet, there are 50 zillion opinions. What is the best way to help him understand that biting people is not acceptable, yet allow him the ability to have his fun?
