The famous dog-walking site Rover.com has crunched the numbers for its annual list of the most popular pet names ... which shows fans are honoring the NBA legend by passing on his name (and nickname) to their beloved furry family members.

The name "Mamba" is up 111% from 2019 -- the biggest spike.

"Black Mamba" is up 58% and "Kobe" is up 16%.

The site says the name "Gianna" is also up 20% from 2019, which Rover suspects is also connected to fans paying tribute to Bryant's daughter, Gigi.

Other notable increases ... Rover says the name LeBron is up among dog owners. Michael Jordan is up big with cats.

Neymar is one of the top trending athlete-inspired dog names of 2020 -- with a 58% increase.

They also note Tom Brady is seeing a surge in pet name popularity ... probably from people in Tampa?!

Obviously, the rise in Kobe-inspired names comes from people looking to honor Bryant following his death back in January.

As we previously reported, BabyCenter is also seeing a surge in people naming their human children after Kobe and Gianna as well.

The name Kobe vaulted from #595 on the list in 2019 to #216 in 2020 -- "far and away the biggest riser on the list for boys in 2020."

As for Gianna, her name among newborns rose from #76 to #24 (seriously, #24).
