My daughter Lauryn is in 7th grade and was wanting to do a science fair project this year using yorkies. Any ideas on what she could do. We have access to yorkie puppies too from Jill. She is just in love with Maddie and was really wanting to do a project using her or different yorkies. She has won the science fair 2 years in a row. Please help us. We cant think of anything. Remember, there has to be ways of testing the theory.
