>Je baise ma chien sur la bouche

Goodness wow. You DO NOT want to be saying that. Baise means "make love to." "ma" may be feminine but "chien" is definitely masculine. Sister Ruth Marie would definitely not approve, in any sense of the phrase

Je donne un baiser sur la bouche de ma chienne. I give a kiss to my dog on its mouth. Je donne des baisers sur la bouche de ma chienne. I give kisses to my dog on its mouth.
