I have an older neighbor who just absolutely loves dogs. He sits by his window all day long and runs outside every time a dog comes by to give them a treat. On hot days he has bowls filled with ice water and a kiddy pool for them to splash in.

I lived here almost 6 years before doing much more than a smile and nod to him, but my next door neighbors with a dog befriended him almost as soon as they moved in.

It wasn't until our son started walking and would stop and try and play in the dog water that we ever really talked to him.
