Dogs can learn new names at any age, so there is no specific age limit for changing a dog’s name. However, older dogs may have a longer history with their original name and may have a stronger association with it, which could make it more difficult for them to adjust to a new name.
If you decide to change your dog’s name, it’s important to do it gradually and with patience. Start by using the new name along with the old name for a few weeks, gradually phasing out the old name as your dog becomes more familiar with the new name. Be consistent with using the new name, and always use a positive and enthusiastic tone of voice when calling your dog.
It’s important to note that changing a dog’s name may not be necessary unless there is a specific reason for doing so, such as if the dog was adopted and came with a name that the new owners don’t like. In general, dogs respond more to the tone and intonation of their owners’ voices rather than the actual words used, so it’s more important to establish a positive relationship with your dog and use positive reinforcement training techniques to communicate with them effectively.
