Is this normal every time we come back from a walk? Toby never has one when out or before a walk but always in the first 5 mins or so of returning, you licks it and stuff which I guess is normal but he's about 6 months so maybe time to get the op I guess, but why does he have big erections as soon as we get back? Is there an instict reason for it? As in does he like me in that way? Or is it a 'teenage phase' hormone release that is trigger from returning from the walk? Will this settle down as its quite off putting or must I have the op for him to calm the hormones?
