A normal human being and a decent parent would get a bag of quarters and find a pretty carousel to treat their child to a pony ride. Then go for ice cream and get an extra scoop of sprinkles. Little kids like to run through the jungle gym chased by other little kids laughing.
Loose the saddle and get the kid a big wheel to ride. Pedaling through a water sprinkler is everything.
Seriously no kid wants to be embarrassed riding a dog!
