Teaching Labrador Retriever to Retrieve
First, I purchased a football. It had laces. After a few tosses, the dog had the laces partially pulled loose.
I threw it. The dog had me fetch it. I threw it again. The dog had me fetch it.
Then, something clicked in the dog and I threw it. The dog went racing to get it. Brought it back to me. I had it drop it. I threw it again. The dog went to get it and bring it back. Three times and then the dog was dragging his tongue across the grass. Enough for today, I guess.
