Probably! Especially since Pluto was not named after the dog Pluto, but after the Roman god of death, Pluto, since it was farthest from the sun and therefore considered to be very cold. Pluto used to be considered a planet, rather than a dwarf planet, and historically the planets were named after Greek Gods.

As for Pluto and dogs, Pluto has a few moons, one of which is named after a dog. Kerberos is named after the multi headed dog who is supposedly guarding the entrance to the underworld (in Greek mythology).

Here’s Pluto and it’s moons.
