Was expecting an image. Glad I'm still a sane person now.
I can't imagine this. Any photos/drawings?
EDIT: Nope, but I found this:
https://answers.yahoo.com/question/index?qid=20151126205332AACG3aQ . I think there was a scene in Alien 3 that depicted a dog getting facehugged, but only that.
Seriously now, do we need to have facehuggers impregnate every animal with a mouth? Judging by their anatomy it seems they're most likely meant for homo-sapiens and its variations, not dogs or animals which have a long snout.
