This isn't totally on topic but I'd walked in a Petsmart a week or two ago. People are allowed to bring their animals to shop with them in the store. There was a couple walking in behind me with a dog. I overheard them talking to another person nonchalantly saying, "It's a stray" ... nearly turned my head and said "What the fuck?"
There's a sign that tells people that they their animals need to have their vaccinations, etc before walking into the store. It wasn't a small dog either. No one knows what kind of disease this dog might have or pass on to other dogs or the temperament of the animal. I'm pretty sure the store is at odds all the time with enforcing the policy but come on, people, good will doesn't mean at the expense of endangering everyone in the store. I zigzagged around another aisle and left. Least it was leashed ... big deal in public places.
I'm afraid of dogs. Small ones are the worst ... territorial, ankle biters. When I was a kid, my aunts had small pomeranians and chihuahuas and they'd tear holes in my socks or chase me around. I know different breeds, owners, etc ... make for a variety of temperaments but I can't stand around and guess. I don't know your dog. Do not want a canine breaking my skin.
Honestly, no idea how I'd react in a situation with an unleashed dog.
