The most basic relations in set theory can be summarized as follows. 1  A set S1 is a subset of set S if and only if every element of S1 is also an element of S. 2  A set S1 is a proper subset of set S if and only if every element of S1 is also an element of S, but there are some elements in S that are not elements of S1.
Then you NEED to feed the puppies yourself. NOT water either, you need puppy replacement milk. Newborn puppies do not drink water. Newborn puppies do nothing but suckle till they ar 4-5 weeks. My dogs pups are 4 weeks old and they are JUST starting to be interested in water and puppy milk soaked kibble. Go get puppy replacement milk from a pet store, petco and petsmart will have it.
In general, puppies don't need to be bathed unless they're visibly dirty or smelly. Puppies -- and older dogs -- need the natural oils in their fur to keep their coats and skin healthy. Most dog shampoos are for dogs around 3 months old or older, but you can still bathe younger puppies if need be.utting a puppy in some warm, shallow water for a shampoo-less bath can be beneficial to both her and you. Breeds that require a lot of grooming will benefit from getting used to bath time at a young age. In fact, a puppy's early introduction to a bath can also benefit you, no matter what breed she is.
