I love using this toy outside with my dog (It's easy to clean and since it is a bright color can't get lost). :) My Black Labrador/Great Dane/Saint Bernard mix loves this toy...the only draw back is that it does not stand up to much tugging (the string holding the "legs" to the ball base started to unravel after a week of rough play.....it is still in one piece though and is still being used....I wouldn't recommend this toy for any tough/avid chewers or unsupervised play.
It floats well so she can see it above the water. LOVE IT! It could be a bit tougher material though as it doesnt stand up to much tugging and chewing by the dog.
