Teaching a dog his new name is very much like teaching him anything else. Similarly to when training the command "come", your dog should learn to associate his new name with treats and attention as positive reinforcement. Give everyone in the household a few treats to keep in their pockets, and ask them to occasionally call the dog's new name and give him or her a treat. Be sure to always say the dog's name in a positive tone of voice. Do not use your dog's name in an exasperated or upset voice or when scolding him and telling him "no." It's important that your dog learn to associate his new name with a positive experience, not punishment and unhappiness. Make sure each member of the household knows this. Try your own backyard or another quiet outdoor space where there are no other dogs to distract him. You could also begin the training process in your own home. You can have him either on or off of his leash. Then give him a treat accompanied by a lot of praise. Repeat this several times over the course of about 5 minutes. Your dog will quickly learn that his new name means he should focus on the caller.  It's important that these training sessions be short because dogs have short attention spans and are easily bored. Try to scatter several of these short sessions throughout the day. When outside of one of these sessions, you should say his name every time you talk to him. Also, you can occasionally say your dog's name when he is not focused on you, but don't overdo it. If he responds, be sure to give him a treat and a lot of praise. After several sessions where you say your dog's name when you have his attention, wait until he is not looking at you before saying his name. Again, say it in your happy and excited voice. If your dog is on a leash and does not turn to you when called, gently pull him to you while saying his name again and giving him a lot of praise and a treat. This will help him associate his name with a positive experience. Once your dog is consistently responding when you call his new name, it's time to slowly stop giving him treats. Start by only giving him a treat every other time he responds and comes when he hears his name. Then slowly reduce the treats until they are longer needed. While it might take your dog a while to learn his new name, if you use the name frequently and always in a happy tone, and consistently give your dog treats and praise, he will soon respond to his new name every time you say it! Don't be tempted to use the dog's old name. Even if you just want your dog to pay attention, or you keep letting the dog's old name slip out, this will only confuse him. If you're still in contact with the dog's old owners (for example, if you were given the dog by other members of your extended family), ask them to use the dog's new name when around him.
