I had a similar event happen at the Petsmart Grooming Salon. I have two dogs and while one was getting her nails clipped, the other stayed beside me and my 8-month old baby. Another man came in and wasn't paying attention to his very friendly spaniel. I was trying to juggle a few things and the spaniel got a little too close to the baby. My very protective pooch snarled at his dog... then the owner commented on my unfriendly dog. Nooo... your dog invaded her family territory. As he was leaving, another woman came in, her turned to her and said "keep your dog away from that one, she is very unfriendly." Fortunately she was sane and when I explained to her what happened she thought it was perfectly reasonable that my dog might not like another dog getting close to her baby.
