My dog is a male mix of terrier and Shih Tzu/chihuahua (don't know for sure), 1 year and 1 month old, his upper tooth from right side just fell out, it is 1cm long and 3mm wide. Is it normal and what do we need to do? What may be the causes?

No, it isn't normal for a one year old dog to suddenly lose a tooth. It could be a retained baby tooth that just fell out, or Myles could have hurt his tooth causing it to fall out. I would have him seen by a vet. He needs his mouth examined to determine if the root is still present, and it will have to be removed if it is.
