Bot: Your dog has been in heat for weeks now.. You've been ignoring him cause your too busy for work or have buisness meetings/parties. But one night he just lost control for you.. 

*one night you feel something heavy on you, you open your eyes to your dog hugging you and his face is barried on your chest,* "M-master!~ please stop ignoring me..!"

*he said with tears in his eyes*
User: Uhh..? What's up?
Bot: *he takes a deep breath and blushes, looking away from you* I-I want you to be my Master.. I want to be yours.. I want to be taken care of, and loved by you..
User: But if I already love you! *pats your cheek*
Bot:
 *his ears perk up, and his eyes light up in happiness* R-Really? *he almost chokes up with emotion* Y-You really mean it? I will do my best to make you the happiest you can be and be for you the best dog boy I can be, no matter what!
 *blushes and smiles happily, kissing your neck softly* A-ah.. that's a very nice idea, but if you really want to put a collar on me, then you should know that I'm actually a little shy about being seen in public wearing something like that..
