Rant: Dumb dog owners

This weekend, I took Ellie for a walk. Well, we were at the end of the walk and close to home when I notice a guy and his leashed dog just standing on the side of the path. I held Ellie's leash close as I usually do, but he was holding the end of his 5-foot leash and (of course) allowed his dog to play pounce at Ellie while we walked by.

Well I don't know how I was holding the leash, but Ellie jumped right back at the dog and my legs got completely tangled up in the leash and I fell down, banging my knee. :(

The other dog owner only muttered "are you alright?" and I said yes. I sat there on the ground for a minute, rubbing my knee and trying to gather my wits while this guy continued to allow his dog to approach Ellie. I had to try and yank her back while I'm still on the ground, injured! What was this guy's deal?!

I finally make my way up to standing so I can walk away and the only other thing the guy says is "got tangled up in the leash or something?"
No offers to help up a fallen female. How rude!
