I have had my dog since he was 8 weeks old, he's 7yrs old now. I'm worried that because he's been my baby for 7 yrs that he will get jealous. He's a big love bug and I pray that he just doesn't care. My neighbor has a 12 month old and he doesn't really want much to do with her (we were trying to get him use to children since he hasn't been around any).  Anyone else been through this? How did you introduce them? And how did it go long term?
