At Bandit's class yesterday the instructor told everyone who had thin puppy collars on their puppy to get a collar which was thicker in width. This is because many of the training techniques we'll be learning will use the leash, and the smaller collars dig into puppy necks more forcefully. The thicker collars aren't as uncomfortable for the puppy in training.
Also, Bandit wanted a name tag just like his brother, Brady, so yesterday evening Mama made a stop at Petco after Costco and got Bandit his first name tag (and it's just like Brady's in shape and color).
