If you have a good eyeglass person they may be able to straighten them out. Mine did that for me all the time since my cats would very nicely get up on the desk and into the cubbie I kept them in and know them on the floor for the dogs enjoyment. It took me the longest time to figure out how the dogs were getting them when I had put them inside a cubbie four feet up.
In answer to your question, it depends on the pup. Some never do.
