Lola loves all balls, you name it small rubber balls, tennis balls, basket balls, footballs, and even my large exercise ball. It's to the point that when I want to exercise with it I have to lock her out of the room, she come running at it head butting it right out of my hands. I attached a short video of her with the exercise ball. If we are in a park or out for a walk and come across kids playing basketball or football she tries so hard to get in the middle of it. They always let her play for a while but of course the ball is to big, I normally have to carry her away while she is looking back and almost crying. One time we were docked on our ski boat and she spotted some guys tossing a football in the water, she dove off the boat and swam so fast out to where they were. She also now dock dives when we toss the ball or toy in the water, she will fetch till the cows come home, never gets tired of it. She is 5 and we keep waiting for her to slow down

LOL I never had such a ball/toy obsessed little dog.
