Having trouble deciding on a dog name for our male golden retriever

We’re getting our pup in a week and don’t have any solid names. [name_m]Leo[/name_m] was going to be our baby name if we had a son, but we didn’t, so right now that’s literally the only name we can agree on. I like it ok for a dog, but I’m not sure if there’s something else better. Goldens to me look like they should have a cowboy name like [name_m]Hank[/name_m] or [name_u]Beau[/name_u], but I hate all the names in that style.

I like nature names, human names, or names of things/characters I like, but my husband and I don’t love the same movies/books.

If it were a female puppy I would have wanted something like: [name_f]Maple[/name_f], [name_f]Hazel[/name_f], [name_f]Mocha[/name_f], [name_f]Meadow[/name_f], [name_f]Willow[/name_f] - nature names mostly

The name I loved that my husband vetoed: Halpert nn. [name_m]Hal[/name_m] (as in [name_m]Jim[/name_m], from the Office). He kind of liked For®est. I don’t hate that one but it’s meh. We didn’t care for the commonly suggested [name_u]Oak[/name_u], [name_m]Birch[/name_m], [name_u]Aspen[/name_u], [name_u]Hunter[/name_u], etc.

What are some boy names that are along the lines of the girl ones I like?

Maybe [name_m]Barley[/name_m], [name_m]Boone[/name_m], [name_m]Buck[/name_m], [name_u]Cedar[/name_u], [name_m]Clay[/name_m], [name_u]Dash[/name_u], [name_m]Farley[/name_m], [name_m]Flint[/name_m], [name_m]Luke[/name_m], [name_u]River[/name_u], [name_u]Riley[/name_u], [name_u]Reed[/name_u], [name_m]Rye[/name_m], [name_u]Wade[/name_u], or [name_m]Silas[/name_m]?
Tried to get a good mix of cowboy and nature here, I hope it helps!

Here are some suggestions (mostly nature but some cowboy thrown in there)
