Yesterday I took Hiro to the dog park since the weather was so nice. When we got to the dog park, there was only 1 dog there and the owner was just about to leave. Hiro and him started to play in the parking lot and then I asked them if they were about to leave. They said cause no one was there. But since I came, they decided to stay. The dog kept wiping his butt on the floor. He may have worms?
Here's a video of them playing.
