Congratulation on the new pup, hope all goes well.

There could be a number of reasons why your pups mom was not registered. She could be registered with another registery, or not registered at all.
Where did you get the pedigree from? Do you have any papers at all on your pup? If this pup is not registered it brings the value way down, if you ever breed her. Hopefully with this questionable background she will be pet only.
Just enjoy her, give her a good home and lots of TLC. She deserves someone like you to take her out of the misery she most likely has experienced in her short life.

Yes, I use Revolution on all of my 12 dogs. I have used it for years and it works great. I like using one item to take care of a multitude of proplems.
