The Dog Who Couldn't Learn Tricks

While doing some browsing recently, I came across this annual called The Treasure Box, undated but from the late 1940s or early 1950s. I was surprised to see that the first item in the contents was The Dog Who Couldn't Learn Tricks, by Jane Shaw, surprised because it was the first I had ever heard of this story; it's not even listed in Susan and Friends. This story doesn't seem to have been reprinted elsewhere. I've found three annuals with The Wilsons Won't Mind, and the same goes for Susan's School Play and even The Onion Man. However, the stories for very young children don't appear to have got the same mileage. Most of them are easy to find because they were printed in the Collins Children's Annual, which enjoyed a wide circulation. However, the three Treasure Box annuals obviously were not printed in such large numbers. But now this long-lost treasure has been unearthed.
