Meet my new OC, Tito the Buddler-Drake.

Buddler-Drakes are a species of dog-sized dragon-sphinxes, kinda. In the wild they dig caves into mountains and hund deer and stuff, but they're also popular familiars for mages all over the multiverse. They can only reproduce when they are happy and content, as they need a certain amount of Serotonin to produce eggs. The eggs are puked out rather than laid traditionally, and they are also not fertilized traditionally: The egg absorbs magic energy from its surroundings to produce the hatchling inside.
