Zara, My RB Cody, part yellow lab, part golden retreiver, was diagnosed with hip dysplasia before he was a year old. Logan, was 2 when I got her, but I noticed problems with her gait and movements soon afterwards, had her Xray'd, and it was determined her hips are awful. She takes glycosomine and an occassional 1/2 of Rimydal for discomfort.

You'll do great on your exams and make an awesome vet!
