Dogs and Nicknames

Does your dog have a nickname?
Mine do. I don't know if this is something everyone does, or just some of us, or just....me. I don't think it's just me. I think you do it, too.
How did your dogs GET their nicknames?
Mine came in a variety of ways.
Dusty = Dustmite. That one is really obvious.
Shiloh was Scooby, then shortened to Scoobs. I shortened it because Scooby took too long to get out of my mouth, and he was so darned fast at reacting to anything. Shiloh acted on impulse before he thought, which got him into lots of sticky situations. This led to me saying "ruh-roh!" which of course is what Scooby-Doo said. That's how he got his name.
Blitz = Beedle Deedle. I don't know.
Moto = Boo-Boo-Bear. It's because he is so cuddly.
Pinch = Dipper. That's because when he barked as a puppy, he'd snap his jaws and bark at the same time, making it a two-syllable bark. Instead of the usual-sounding "woof", it actually sounded like he was saying "Dip-per!" It's cute. It stuck.
Along with each of their nicknames comes a little sing-song that each dog has. I did an experiment recently to see if each dog understood that a particular song was for them. I sat on the couch, not making eye contact, just looking straight ahead, and softly sang one of their nickname songs. Sure enough, that individual would brighten, wag their tail, and step forward. Dusty is largely deaf now but back when he could hear his song he did this cute little back-and-forth with his head and begin prancing; so cute!
Shiloh adored his song and would try to match the pitch of my voice when I sang it to him. The two of us would "sing" it together.
Blitz wags his tail and spins.
Moto makes a very low "whuh" and rolls over on his back.
Pinch, of course, snaps his jaws at me with delight.
I don't know how the songs were born. They just sort of happened. I don't try to make a song, they just seem to come along in their own time.
It just seems to come with having a dog.
