Just remind me how common toxicara is?

So how do we deal with dogs to your satisfaction without imposing bans and restrictions (and in the process strengthening the hand of those who would advocate for the risk averse, nannying society)? Surely better to put up with the slight risk of dog-related ill health and the greater risk of dog-related nuisance than the massive risk in throwing our hard-won freedoms away on(relative)trivia?

Professionally, meanwhile, I'll leave physical health to them as likes that sort of thing... yeulch!
