Introducing a new puppy

[Kym]

I just got a sweet little baby girl miniature schnauzer that I named Eevee. That being said I already had my sweet baby boy toy poodle kiba he's 3 years old. He's super playful and absolutely loves my mom's 3 dogs. So I figured when I brought Eevee home they would become quick friends, but I seem to have mistaken. He seems completely terrified of her which is oddly funny, as she's half his size. I just brought her home had her for no more than 3 1/2 days. He doesn't want nothing to do with her, or the things she's "touched" he won't even play with his toys after she's got a hold of them. He didn't even want anything to do with me after I got her. I still show him the same amount of attention, and make sure to give him some one on one time, but he doesn't seem like the same dog. He is somewhat tolerate of her. He at first wouldn't even come off the couch but now he'll walk around the house as long as she doesn't come close. The minute she starts going towards him he runs off. I've introduced him to other dogs before and he loves them. My mom says it's because she's a puppy. Eevee absolutely loves him. She follows him around, and will stop whats shes doing when she sees him walk off. She often sits on the ground stirring up at him wagging her tail as he sits on the couch staring at her. He barks at her or me often when he doesn't like something. Usually when she's staring at him, or when I play with her. So what I'm wondering is when will he get use to her or accept her? Is there a way I can get him to warm up to her faster?
