It’s truly hard to say what and how puppies understand their given name. Sure they hear the sound, and we all know that they are sure to react to it. However, experts say that it doesn’t mean they realize that the word or the name they are hearing and called for has anything to do with their “self.”
Owners don’t just use the puppy’s name when they are calling them. They also use it when talking to about their pets with their friends. As for example, A puppy hears “his name,” called by his master, he looks up, but no one either the visitor or his master is giving him any attention. He shrugs, and goes back to whatever he was doing. There is a high possibility that the next time someone calls his name he will not even bother to look up. He will think the he has no reason to react to it anyways. He has now been desensitized to his own name. For this reason, some trainers have owners give their puppy pet two names – one is used to address their pet while talking to him and another name to use when they’re talking about him in front of anyone.
