Is the [draco vulgaris](https://discworld.fandom.com/wiki/Draco_vulgaris) (first described in [*Guards! Guards!* (1989)](https://wiki.lspace.org/mediawiki/Book:Guards!_Guards!) inspired by the [pseudodragons](https://forgottenrealms.fandom.com/wiki/Pseudodragon) found in *Dungeons and Dragons*?

I recently learned about them and find many similarities:

* small winged dragon (around than 2 feet long)
* can be a pet
* (relatively) short lived
* limited ability to communicate

Since D&D has many versions, I face difficulties identifying when pseudodragons were first defined but they [seem to be mentioned in a first version (1977)](https://forgottenrealms.fandom.com/wiki/Monster_Manual_1st_edition).

Digging around this topic, I found the [small pet dragon trope](https://tvtropes.org/pmwiki/pmwiki.php/Main/ShoulderSizedDragon): it seems to be even older?

Does anyone have a Terry Pratchett interview or discussion about this topic?
