Have you been a victim of a DRI -- Dog Related Injury?

Am I just stumbling into this phenomenon late, or has there been a rash of dog-related injuries lately? I'm not talking about attacks, I'm talking about dogs at play slamming into their owners or bystanders and causing serious injury.

In the past couple months, two friends have been sent to the hospital after being run into by dogs. One required surgery, the other rest after being diagnosed with a concussion that came from a fall. A couple years ago, another friend needed surgery after being run into by a dog at the dog park.

When the topic came up around the office, others chimed in. One dog park regular says he's seen people carted off at University Lake on multiple occasions, all victims of rambunctious dogs. He says he's seen it most often when two dogs are roughhousing with each other and are oblivious of their surroundings.

Another, one who required surgery after a dog hit her from behind, says her surgeon says doctors even have a code for it, DRI -- Dog Related Injury.

I doubt this is anything new. It's probably been going on for as long as humans have owned dogs.

But what can you do about it? Does anyone have a suggestion on how to avoid injuries when at a dog park or anywhere dogs are playing together?

Here's what I do: I keep my eyes on the dogs and my knees bent. I think my knees have a better chance of withstanding a collision if they're not locked and rigid. I have been run into by dogs and walked away from it, so the technique either works or I've been lucky. Probably a little bit of both.

How about you? What do you do to say safe when dogs are at play?
