Our Waya was 3 months when we got him and his ears were down. The girl that we bought him from had not cut the hair on his ears. When we got home, I shaved his little ears with hubbys mustache trimmer and they went right up and have stayed that way. I shaved it a little more than what I had read. I just totally shaved it from halfway down to the tips and then trimmed the outside of the ears VERY carefully. He was a handful and still is.
When we got Chuhga, our first baby, I was so afraid that she would get hypoglycemia that I put Karo syrup in her drinking water. I have never had a problem with it with either of the yorkies.
