Did anyone noticed that OP mentioned TWO toddlers and a dog?
Yeah, keep the kids and get a Pit!
A bike inside the house is not safe from little grubby hands no matter where you stash it. One toddler will lift another while standing on a dog. Little grubby hands are not hands safe either - one is getting caught in front or back derailer while sibling is happily turning the crank....I am thinking about storage case bolted to the floor in the garage and bike chained to the floor inside the case.
The cemented anchor idea sounds very plausible. However, the cemented anchor plus the Pit combination sounds absolutely failsafe!
