I absolutely agree with everyone, especially Bailey's Mom my words exactly! I couldn't have said it any better. Your not being over protective or paranoid. I take my male to the "BarcPark" down here it's completely enclosed/fenced in, packs of dogs of all sizes.....unfortunately he is very out going and goes up to every dog with no fear! He will growl or even snap at another dog, if he feels he has too? I do not promote aggressive behaviour and that's not what he is doing. He is just letting them know his boundries. I do stay very close and I reassure him that I am there by saying "It's OK. I'm here" if he feels unsafe or unsure of the situation he jumps up in my arms. I cannot change his personality nor do I want to. I just keep a sharp eye out for him, sometimes you have to anticipate what might happen and be prepared to react in any situation? Be ready for anything, expect the unexpected! After all it's up to do what's best for them.
