Hi uplink, sorry to hear that…..
I’ve experienced similar with bullocks (ie bovine teenagers) but they fold if you stand and wave/shout (*but with a kid and a dog, I’d do a runner as well, to be honest I’d ditch the dog as well…, as I suspect thta it may be the issue, maybe not though)
I’ve also seen food stampedes, ie get fed by people, therefore people = food, charge ….
I’ve had significantly more problems with dogs, horse riders and ramblers than I have with cows (and I’ve more or less had a head on collision with a full sized bull), however I also remember number 39, a cow on the farm I worked on, it would come for 1/2 a mile to have a go – it really had some problems.
I guess it’s a bit like people, some you do have to watch out for, the more experienced with animals you are the better your judgement is likely to be.
