If you've got a new dog or a brand new puppy, don't wait for bad habits to begin. Start your dog (or pup) from Day 1 with a clear set of rules and teach him what those rules are. To do this, you might want to start by making a list with two columns: MUST NOT DO and WOULD LIKE TO DO. Fill those columns up and then take a look at what you've got.
- get on furniture
- bark at other dogs
- pull on the leash
And in the WOULD LIKE TO DO column, you've got these:
- come when called
- sit politely for petting
- sit before going outside
It's a good idea to get input from everyone in the family and then finalize the list together. You want everyone on the same page when it comes to the rules for the dog.
