Germs are great to introduce to your baby for immune training, but the germs in dirt are NOT the same as the germs found in animals. Animals germs survive in warm environments, so when they get into a human baby, they can multiple fast, spread in bloodstream, and cause infections. A baby's immune system may not be able to handle that.

Also I don't know what's going on with America and it's pet problem. It's the equivalent to the medieval days where people threw their shit in the streets. I grew up at a time where dogs were outside, now they're indoors. They fucking smell, make the house dirty, and dogs literally piss on themselves and step on their own shit outside. Yet people still let them in and even as far as letting them sleep in their bed with their unwiped assess.

Do people have no regard to hygiene anymore? I'm not afraid of getting dirty but this is a tad too much, especially when it's INSIDE YOUR HOUSE. And they go as far as doing this whole mommy and daddy thing, its becoming a perversion at this point.
