7 plus dogs involved apparently which is why people are thinking a breeder. But there are also a couple of boarding kennels nearby plus the area is very popular with dog walkers and you often see people with 5 or 6 dogs on leads, professional dog walkers. There is also a traveller presence in the area at the moment, plus a permanent camp (or was, it might have gone recently as the land was up for sale).
There has been a large increase in animals being attacked in fields over the past few years, since lockdown I guess when everyone got dogs. I often cycle or walk at a nearby airfield popular with dog walkers and I've pretty much had to stop as I was sick of being chased by dogs. As usual, owners not dogs etc but there aren't many breeds capable of killing an adult woman. RIP.
