I'm glad your mom went to the breeder, got to look for herself and be apart of the process,
plus it will take some of the pressure off you. I definitely think its harder to pick out a dog for someone else.
As far as names go, this website has a list and you can look by gender or letter:
The Pampered Pup, Designer Dog Boutique: Dog Clothes, Dog Clothing, Dog Beds, Dog Toys, Dog Collars, Dog Carriers, Dog Names, Puppy Names
Congratulations (to you and your mom)!!!
