My Dog's Name

That I'm unable to answer with authority, but probably to the dog it doesn't matter.

To you it might matter because your consciousness includes the alphabet and the concept of numbers. Thus, the name you know your dog as may modify or filter how you regard your dog.

Note that the cornerstone letter of your name and the open heart letter of your name are identical to Mandy's name. It is good to be so. The attraction of identical and similar resonance may be a reason not to change it.
