We lost our bestest buddy Pixel about 6 months ago, and earlier this week met this guy:
He was left in front of the vet clinic in a shopping cart. I just happened to be there with one of my dogs on the first day they could legally offer him for adoption. He is very small; maybe 6 pounds soaking wet? I’ve suggested Quark to my son as a name, but he’s not biting. So to speak. 
Any name suggestions for a small, slightly timid but very scrappy little dude?
Garrus, after Garrus Vakarian, the turian squadmate from Mass Effect.
Pixel or Lemmy.
Well, our dogs throughout the years (just to name a few) were Toby (because he was a wanderer like St. Tobias), Sandy, Tiffany, Monty. Our first deviations from the ‘-y’ thing were Joy and Willow, whose names I never really liked.
Got to tell you, Sandy was our cocker spaniel mut mix. I wanted to call her Muffin when I was nine, and we first got her. But my mother said she was a good-sized dog, and Muffin belonged to a small dog.
So hey, you can have Muffin

Minion.

If he is stand-offish, name him Kitty.
If timid, Hamster. (You can call him hammy for short)
Looks like a Pikachu to me.
Albeit a very serious one.
He looks like a Fyodor to me. As in Dostoyevsky.
Mookie.
mmm
Mouse
Looks kind of like a bat. How about Foxbat? Or Foxbatman?
Found in a cart, looks serious and philosophical…
How about René.
I think there might even be a slight resemblance, compare their eyes.
I like what Pee-wee Herman named his dog – Speck.
Upon Reflection, David Bowie.
I missed this somehow. Oh, that’s right. I drink.
Yes, Rene De Cart is the obvious choice. Very well done, Riemann.
Begbie.
Looks right to me. Dogito ergo sum.
Gunter.
Seems like a Rocky to me. Just sounds right.
