AlaskaYorkie - you are too kind!!! I need to update those videos...

SJK - it is never too early to teach a dog tricks. In fact, I think that it's good for them to learn "how to learn" early. Perhaps what those people were thinking is that it isn't good for young dogs to do too much jumping. The growth plates in their bones don't solidify until about 12- 18 months of age and too much jumping can do damage.

And no, I personally don't think their small size negatively impacts their learning in any way.
