No dog can ever be entirely trusted - big or small, whatever breed. Ideally, of course, dogs and children would be kept apart or supervised at all times, both would be well trained in how to behave towards each other. For instance, youngsters will stare at a dog - and the dog will see it as a threat or challenge.
My little JRT is, statistically, amongst the breeds most likely to bite. Do all the statistics allow for the sheer number of common types of dogs, though? What about the increase in (lockdown) dog ownership?
Jaw size is important too. The damage done by a nip from a small dog is incomparable with that from a wide, large, strong mouth.
Yes, I'd like more education on pet ownership responsibilities, on parenthood, too, with increased safety awareness - perhaps not legislation, though, that will be ignored.
Every death's a tragedy, the four kids a year killed by dogs - and the one every week murdered by humans (so called).
