I think i like my pets/animals more then family, is this a bad thing?

I think i would be sadder if my dog died, i raised her since she was a puppy now she is 5, she sleeps on my bed every night, comes with me everywhere i do, and in winter she is a very good sled dog for fun, (im 15) but i feel like i care for her more then i do my family, i feel like i would be more sad if she was gone then if a family member was lost, is this a bad thing and is this wrong? Thanks
