Go for it!
I got two sisters at once so I've had two for awhile.. They had each other to play with and kept each other company. A lot of people said they'd grow up attached to each other and wouldn't bond to me, but thats not the case with my two. They both love me more than they love each other..lol
I just added my third girl Tuesday.. She's a biewer and is a great addition! The girls took to her right away! Bailey is my barker and since adding Bella this week, I guess she's happy because she can have a reason to bark now..

Her and Bella (my biewer) have the biggest mouths. Brooklynn, Bailey's sister, is soo quiet and shy! But they all compliment each other very well!! I love having three! It's no different than having one or two! A lot of people say vet bills can be the only downfall, but my vet only charges one office visit for everyone and they usually don't charge me the full price for medications or anything I need for them.
