Traditional Dog Training Versus Positive Reinforcement Dog Training - A Comparison

Recommended Answer:
Put the treat in your hand
Close hand
Both hands out
Say "which one?"
If the dog taps with its nose at 1st, release the treat then as the dog picks up on that make it harder and wait for a paw to tap it, make the dog work out that a nose is no longer going to cut it and it will work out he needs to work harder and will eventually figure it out. Helps if your dog knows to "give paw"

• Training is the best investment you can make in your relationship with your dog. You'll need to do your homework first, though, to learn how to communicate what you want in a way that your dog will understand. Stay consistent and patient, reward your dog for getting it right and remember: you can train a dog of any age.
