Am I ready for a new pup?!?!

So for you that know, Snickers isn't doing very well, which in return.. I'm not doing very well. Pretty much it boils down to 6 grand worth of surgery, and keeping her off of her back leg for a whole year... yeah never gonna happen! Anyway after a month of many crying sessions, and family talking, Snickers and I have decided to get a new member to our family! We have have been looking for a little girl puppy for the last couple weeks, and we FINALLY! found one!

She is only 6 weeks old right now, so she can't come home till the first of October, but we are so excited for her! I'm a little nervous, you can't tell Snickers this, but the reason for us getting a new puppy, is cause I'm not sure how much longer I'm going to be able to keep Snickers. I'm being a little selfish in the fact that I wanna become attached to another dog, before I have to put her to sleep. Everyone keeps asking me "are you sure about another dog?" "Your ready for another dog?" "That's alot of work, you want a new puppy?" would people stop asking me that, no of coarse I'm not, they are alot of work, but Snickers has been the best thing that has happen to me in my life thus for, and I'm not sure what I'm going to do without her, and this is the best way I can think of to deal with it. So our new puppy is a choc. lab or coarse. We aren't sure about the name though, any ideas? We kinda wanted to stay with the candy bar theme, seeing how we have a Snickers, and a Hershey, so any ideas would be greatly appreciated!
