Hi everyone! I just adopted a 5 year old Yorkie baby. My family and I have barely had her a week, and she already has me wrapped around her finger. I have a few questions. First, her previous owner had her on Sentry Pro (over the counter) for fleas and ticks. She weighs 4 1/2 lbs. What do most people get from the vet for their babies? I have a vet appt scheduled for this Thursday. Next, what foods are good for these little ones? She's been on Purina Special Diet. My chihuahua eats Natural Balance. Any other advice anyone has is appreciated!
