Steve said that dogs frolicking in the waves with children is unhygienic. For the dogs or the kids?
Someone said earlier that they thought small dogs were more likely to bite and this is statistically true, but is also an example of the inadequacy of statistics. I'll use my two dogs as an example. One is a 65lb pitbull and the other is a 12 pound chug. The chug, Emma Rose, hates everyone and would much more be inclined to nip someone than Bagel the pittie who likes most people. The difference is the potential for damage. If Emma bit you the worst scenario would be a tiny puncture you might want a pinky bandage for. Now if Bagel ever did decide someone needed biting, he could crush bones. Of course I'd never allow that. On the rare occasion that he does take an instant dislike to someone he gives fair warning with his "I mean business" bark. I keep him on a short leash at such times, but I also trust his judgment.
If anyone wondered what a chug is, it's a cross between a chihuahua and a pug. When my wife said we were getting such a hybrid I said it should be called a chi-pug in honor of 70's all-female punk rock band, Chi-Pig. But my wife said "It's already a thing and it's called a chug!" But then, when we had Jack Russell/shit-tzu mix I told anyone who asked that it was a Jack Shit.
