In fact, when Im teaching an obedience class I always have the dog owners start by teaching their dogs ATTENTION.
85% of the time when your dog does not perform the command, there is a good chance that your dog is not paying attention. So always start by teaching attention. I like to just say the dogs name to get his attention. Some people like to teach Watch Me or Watch.
Heres a video of me teaching attention.
So remember, get your dogs attention before you give a command.
All the best,
Eric
