Indeed, they are.
My reptile forums regularly break out in flame wars over photos of people draping their snakes/lizards over their dogs or allowing them to “cuddle” with cats.
The cat/dog owners always get butt hurt over the admonitions but facts are facts.
In less than a second, Fluffy or Fido can fatally injure your beloved reptile.
Why risk it?
When I was teen, the first thing I taught my Dobes was respect and gentleness for kids.
The breed is inexplicably crazy for children anyway but more is better.
[I suspect the Beauceron/herding dog influence accounts for it]
Around kids, my great concern is being yanked off my feet because the Dobes spotted a kid across the store and want to fly me like a kite so they can go worship it.

I never knew that about Dobermans, having been terrified of the one which lived down the street from me when I was 5 or 6.
