I had a foster named Niko he was adopted out a few months ago and I got a call from the new mom. They took Niko to the lake in town and there was a bulldog(? her name) there that was chasing a ball in the water and bringing it back to his owner. Niko jumped in the water scaring his new papa half out of his mind. While Dad on on shore frantically stripping off his shoes thinking Niko is going to drown, Niko is very calmly swimming out to the bulldog took the ball right out of its mouth and swims back to shore very proudly showing his dad what he found. They can't keep him out of the water now.
Niko is a 6lb chihuahua. :-)
