Hi everyone, proud owner of a ten-month sheltie boy, and I'm wondering if it's worthwhile getting growth plate x-rays. From what I've found online most people seem to think that 18+ months is when they're fully closed, but Gormy's definitely on the small side (ribs are faintly palpable at 12lbs). If he's going to be a smaller dog, will they close earlier? I don't want to waste money on the x-ray if there's no way he's mature though - I'll just wait until he's 18 m/o. I want to get him desexed so he can start going to doggy daycare, and also so he can start doing jumps.
