It would help if folk knew how to behave round dogs and respect them for what they are.
Dont bend over the dog and instantly waft your hand its face. Nobody would like that done to them.
Dont approach any dog without asking the owner first either. Get on their level and let them sniff the palm of your hand.
They soon figure you're not a threat and you soon find out if the dogs is sound or not.
See so many people fanny about dogs.
They sense nob heads.
