3. Yorkshire Terrier
This little love grows to be about 4-6 pounds in weight and only 8 to 9 inches tall. Their average lifespan is anywhere from 12 to 15 years. This is undoubtedly the most famous of the very small dog breeds and they are good inside dogs. They make take a while to adjust to new pets but they can be raised with other pets. You will want to crate train a yorkie (as they are affectionately called) because it can be somewhat challenging to house train these little ones. They will be able to get along with your neighbors pet’s once they get to know them. These dogs do not shed much but do require daily brushing so their coat doesn’t get tangled. They are prone to digestive problems, barking and dental problems. They can be trained not to bark with patience though.
