I agree with Veronica. Can you sit down with your daughter and kind of make it her choice? She's obviously very interested in animals... And if you're worried about the same attack problem happening with the new dog, maybe you could have him fixed?

I just scrolled back up to write in a little warning here. I'm about to go off on a rant about how awesome it is to work with dogs. This might be something you already know, or have NO interest in, but here it goes :
I have two dogs myself, that were both rescued. We had one for 5 years before we got the other one. They were pretty "screwed up", from what had happened to them before they were rescued, and especially the last one required a lot of training work (in addition to my home cooked doggie psychotherapy ).

The reason I'm bringing this up, is that I just want to share how very rewarding the process of training has been. Since this puppy is a "clean slate", he would probably really fun for your daughter to train! I really can't say enough about the bond you create with a dog doing this.

I have done positive only training (kind of a must with abused dogs...) and used a clicker. We have a loose knit training community where I live. The "leader" is a wonderful woman trained in positive training. Your daughter might love something like this!

Ok, that's the end of my rant.
