The only time that we ever had a 10 year old at home alone, was by accident when the school had to shut down early once.
(no pit bull either)
An average 10-year-old can be responsible for himself, and watch a movie with a little brother, briefly. But a dangerous dog is something totally different - it’s funny how you never hear about a young child’s (or a passing stranger’s) being attacked by a family’s cat.
