Starting with our very broken first foster puppy (now family member) Mr. Stix who arrived at our local shelter with 15 fractures -- all four legs, his hips and his tail, we started specialize in fostering dogs who've likely been hit by a car or similar vehicle. For example, with Mr. Stix, we wonder maybe something more like an ATV since clearly the wreck didn't kill him or cause any internal organ damage (that we know of). As we learned, though, from the unexpected death of foster puppy Dream from an undetected internal injury, no guarantees about how a dog broken leg situation will turn out. With so many injured dogs and puppies in our experience bank, I figured I'd share a few dog broken leg cast tips. Yep, that's a keyword. Sorry it's weird.
