If you are considering purchasing a Rat Terrier, and you want a certain Size, you will want to take that into consideration when you are looking at litters. A lot of times you can tell how small, or big the dog will be by looking at the other dogs in its lineage. Take a look at the mother and father. Ask the Sizes of their parents, or how big their previous litters have grown to be. These facts will give you an idea of the Size the puppies in that litter might be at adulthood.
One thing to consider is you may want to try to get a puppy from a bigger litter if you have small children in your home. Small children can accidentally hurt or even kill a very small puppy. Smaller puppies are also more fragile in general, so take your lifestyle into consideration when you are choosing a puppy.
