Cutting your toenail too short or rounding the edge of the nail can cause it to grow into the skin. Wearing shoes or socks that don't fit well can also cause an ingrown toenail. If your shoes are too tight, they might press the nail into the toe and cause it to grow into the skin. You can get an ingrown toenail if you hurt your toe, such as stubbing it. This can cause the nail to grow inward.
However, jockeys tend to be shorter than normal to meet the weight guidelines. The average height for a jockey is between 4 feet 10 inches and 5 feet 6 inches.
The Miniature Poodle stands 10 - 15 inches and weighs 15 to 17 pounds. The Cocker itself (which is usually the dam in the mating) stands 14 to 17 inches tall and weighs 25 to 34 pounds. The mating produces a Cockapoo somewhere in between the two, standing 10 - 15 inches tall and weighing 6 - 20 pounds.
