Dear Chronicle, This past Mother’s Day, around noon, just up the hike-and-bike trail from the Stevie Ray Vaughan statue, my girlfriend was jogging; a dog knocked her down; she fell and hit the back of her head, had fairly profuse bleeding from her scalp, was woozy, and had to wait a few minutes before getting up. She went to an emergency room where she had to get stitches in her scalp. I was not there when this happened, but a couple of bystanders helped her. One in particular – a lady who said she is a dermatologist – was most helpful. Thank you! However, the owners of the dog were all about downplaying the injury and not giving out any info on who they were. My girlfriend is an animal lover and was clear that the dog didn’t do anything vicious – it merely responded a little over enthusiastically when the owner whistled for it. I agree – the dog’s not the problem – it was an accident. But I hope the selfish, thoughtless, uncaring, arrogant, self-centered asshole owners are fucking ashamed of themselves. Note to anyone who may have witnessed this – they had three dogs – a border collie (the accident culprit), a German shepherd, and a nondescript mix. Again, the dogs are cool; it’s the owners who suck. If you see them, please tell them.
