I have three: Poncho, he's a three year old Chihuahua , Princess she's a two year old Yorkie and Mandy she's a 9 month old Rottweiler.
Weird mix of pets I know, but they all get along great. Mandy thinks she's a lap dog, shuch a sweetheart she is. We had another Rotti, Roxanne, she passed away at 12 years old. Poncho & Princess missed her so much, when we went to the vet a Rottie was there, they ran up to her, I came home and told my husband we needed to get another one, so we did. They are all best friends.
Oh, Princess is the only one who sleeps in my bed. Poncho & Mandy found room upstairs with the kids. We also have birds and fish. With five kids, and lots of pets, there's never a dull time in this house!
So no, your not nuts!
But I think I might be! LOL
