No la, because as you see, in Buddhism there are six realms, the
3 lower realms are hell, ghost, animals, higher realms are asuras,
humans, devas (heaven). So if you have pets, it creates "ignorant
affinity", which I quote from my master. Animals belong to the
ignorant catergory, which is quite obvious why, that is why I said
that.
When you marry, it creates the affinity that binds u and her under
samsaric rebirth together. In chinese its called "chan yuan" but i
dunno the english name. Best is to have "Fa yuan", like now you and
i have "fa yuan", or "dharmic affinity".
