I have a 14 month old Australian Shepherd. She weighs about 37 lbs and seems to be done growing. Recently I've noticed almost every time she gets up from a laying position I can hear what seems to be her hips/back joints making a popping/cracking sound. If I'm not laying right beside her I wouldn't be able to hear the popping. It reminds me of when I get up and have a few pops. She loves to play and doesn't seem to be in any sort of pain. She does kind of have a hopping gait when she really gets running but other Aussie's I've seen tend to have that same bouncy gait at times. I was planning on getting her hips x-rayed at 2 years. Should I take her in now? Could this really just be growing pains? I think I'm just being paranoid but wanted others advice. Thanks!
