My four year old grandson absolutely loves Clifford the Big Red Dog. We have borrowed every DVD they have at our library many, many times. Some of his favorite titles are: Clifford's really big movie, Clifford's dog house, Puppy love and Happy Birthday Clifford. Although you can probably borrow them from your library, they can also be bought at many stores and online for only around $10.
I have always read Clifford books to my grandson, but when I am not able to read to him, these DVD's are the next best thing. The movie's are in cartoon format and are very entertaining for younger children. They also can teach valuable lessons about sharing, making friends and helping people. Each DVD has several different stories that are short enough to keep a younger child's interest.
I would highly recommend you introduce your child to Clifford the Big Red Dog, if you haven't already done so.
