Speak is another easy trick to teach your dog. Excitedly tell your dog "speak." Keep repeating your trigger word in an excited voice and your dog will begin to get excited. Eventually, out of excitement they will bark. Once your dog lets out a bark, reward them with a treat and love and affection, repeating speak, good girl/boy! Try this a couple of times to make sure they got it. As with all training, repetition is key.
