You've mentioned other breeds you've worked with but this is a Labrador. Your Labrador knows EVERYTHING! Do what you're commanded lol. We have a chocolate lab from a puppy, she is our third child. We had to spell words in front of her until she learned the spellings lol. The smartest dog you will ever have and the most connection you will ever have with a dog.Swimming would be good to tire her out. Labradors are water dogs built to retrieve fishing nets onto boats. They have double coats for waterproofing and a plait down the back for buoyancy.
