As Cesar Millan of The Dog Whisperer says, most discipline problems are rooted in a dog not getting enough exercise.

Enter: the Springer.

I bought one’a these handy “Springer” dog-bicycle attachments off ebay a year or so ago, and finally got it on my bike (well, I had the handy gents at UBikes mount it for me, I was born with 10 thumbs and zero mental capacity for assembling anything harder than my morning coffee). It works like a charm—the spring prevents Redford, my mutt, from pulling my bike outta whack if he should happen to see a squirrel or get scared by a noise…and the Springer itself prevents Redford from running toward my bike, which would be bad. Finally, if we bike into a pole or tree or somesuch, separating Redford and my bike, there’s an attachment that breaks free, ensuring Redford’s safety (and mine).

It’s a great way to get the little guy some much-needed exercise—and unlike biking around with his leash in my hand, it enables me to have two hands on the handlebars, ready to brake at a moment’s notice (I was hit by a car a few months back while riding with Redford, and probably would have been able to brake faster and harder if I’d had…duh…two hands on me handlebars. Red, oblivious to my near-death experience, hopped in the car, ready to go for a fun trip who knows where!). Finally, the Springer slides off when not in use—very convenient.

Problems: I still ride with one hand holding Red’s leash frequently, esp in the morning, as the Springer doesn’t well allow for Redford’s sudden decision to go pee or poo. For another review on a favorite site of mine, go to Bikehacks.com: “At $69 for the Springer Black colorway and $74 for the Springer Chrome colorway, [the Springer is] slightly more expensive than the WalkyDog…”

And then there’s also the Biker Dog, which handily doubles as a leash when you’re done biking.
