New Puppy

My family and I recently got another dog, and to many this is a surprise. If you knew our family you would know that is a big step but we did it anyways. We got a seven week old mix of Rhodesian Ridge-back, Lab, and Shepherd. We decided to name her Riley (even though it should have been Grace since she is very graceful). My sisters and I have been taking turns keeping her at night since she is still little and is in the process of being trained. Our biggest fear was introducing our puppy to our other dog, which is a twelve year old pure bread beagle. She has ran the house since we got her and the little one was not taken likely by her. After about a week, our older dog jumped on board and now they like each other. She had her first vet appointment yesterday and we found out she weighs 8 pounds. She starts Puppy Preschool on Saturday. :) She is also scared of everything and anything; plastic bags, trash cans, cars, black shoes (really anything!).
