My 5 month old Boston Terrier bit my mother because she wouldn't let her jump on the couch and last night she bit me! Is this a personality issue or a training problem?

What you are describing is pretty normal adolescent/puppy behavior when a puppy isn't given enough management.

By management I mean when we raise puppies here we don't allow puppies the freedom to jump on and off the furniture and we try to set them up for success by not getting down on the floor with them if they are the type that get excited and overly aroused by that. I know many Bostons and they tend to be high drive, energetic dogs that need to be taught how we expect them to behave in our home. Since they are puppies and don't have a lot of life experience or training history we use management tools to prevent the wrong thing while we create a training relationship with them.

My puppies are on a leash at all times unless they are in their ex pen or crate. That way I can block them from getting on the couch or sneaking into another room, etc. With excitable and rowdy puppies (which is many of them) I don't sit on the floor as it encourages behaviors I don't want.

We have lots of content on our website about managing puppies and we also offer streaming video that outlines how we raise dogs here in our home. We always have a multi dog household with a range of breeds from working German Shepherds and Malinois to terriers, cattle dogs, shih tzus and recently we added a Chihuahua to our family.

I'll link some resources for you below.

You're most welcome!
