It also depends on what part of the bookcase he hit. If it has sharp edges, that would do way more damage or hurt more than hitting the side straight on, only bc I've banged my elbow a few times.
Also, the age of the dog as to how developed his bones were. My puppy at 5 months took a bad step off the last step onto a concrete landing and banged his head. He showed neuro signs immediately and that was less than a 6 inch fall, and at a very slow speed. He was rushed to the vet immediately and did survive.
Maybe a radar gun like they use for speeders or to clock pitcher's speed in baseball, or just a stopwatch. I could and my Tink is fast, but she may have a hernia so I don't want to push her... if she's okay after her vet appt on Wednesday, I'll get a time/distance for you. |
