Yes, dogs and cats are the most common cause of falls in the US I think I saw it was like 80% of all falls. I had a neighbors dog jump on me without warning, it knocked me over and I fell directly on my hip on pavement! I survived that fall, I think, with just a bruise. I know someone, someone with osteoporosis, who came outside and their neighbors huge dog (like the 3-4 ft. kind) all of a sudden jumped up to "give then a hug". The person fell back against a wall thankfully. That was scary.

How in the world can people own dogs and not have them trained? In Europe dogs get trained by the entire society starting very young. The method is to bring them out into all situations and no one comes up to the dog to pet it. That's totally different than in America! That early attention and petting causes bad dog behavior. I think I read it causes a type of neuroses in digs.
