Soft puppy names?

So this is for a puppy, not a baby, but I still think that this would be a great place to ask. I’m trying to decide between a list of names, I’m also open to suggestions on 'softer sounding boy names that would work for a blue [name_u]Merle[/name_u] Australian shepherd. So far our list includes:
[name_u]Luca[/name_u]
[name_u]Sacha[/name_u]
[name_m]Jasper[/name_m]
[name_u]Percy[/name_u]
[name_f]Juno[/name_f]
[name_m]Atlas[/name_m]
Blueberry ([name_u]Blue[/name_u]) -my younger sister’s absolute favorite.
I don’t want it to be too feminine, easy to shout, and one that would fit both a 5 pound puppy and a 60 pound full grown dog. Thoughts?

I like [name_u]Luca[/name_u], [name_u]Sacha[/name_u], and Blueberry! :slight_smile:

I have a dog named [name_m]Jasper[/name_m] and he’s the cutest! I also like Blueberry.

[name_m]Jasper[/name_m] & Blueberry are great!

I love [name_u]Luca[/name_u]! I would suggest [name_m]Louie[/name_m].

I can so see [name_m]Jasper[/name_m] or [name_m]Atlas[/name_m] on a [name_u]Blue[/name_u] [name_u]Merle[/name_u] Australian [name_m]Shepherd[/name_m]. Currently preferring, could change in an hour, [name_m]Atlas[/name_m].
