Yohoheaveho the ones I saw on FB were prosecuted under the Dangerous Dogs Act, but my friends' incident wasn't because they couldn't trace the dog/owner. But to be honest, it happens so frequently (that dogs are off the lead and chase horses and other dogs round here) that I have safe, private routes to ride on that I stick to. I have noticed that when I travel to other parts of the country, dog owners are more likely to have their pets on leads and to be polite!
Even the risk of a loose dog chasing my horse and causing him to bolt is too high. The beach is just far too risky now due to loose dogs. It just takes one to bite through a tendon, and your horse would have to be ots.
I didnt even report the dog that bit me to the police, as I didnt want its death on my conscience. It was a rescue. Perhaps I should have done. I heard I later it had attacked a couple of peoples'dogs too. I ended up in hospital to get the wound cleaned and on strong antibiotics for 2 weeks!
