My girl loves playing fetch but she's only five months old and I'm not throwing the ball real far. But after a couple dozen times or so, she flops down like she's totally exhausted.One other thing you should know - bassets absolutely do not fetch. If you throw a ball they might get it once. Maybe even bring it back (or maybe not). But if you take it away and throw it again, they will just look at you like "well, I guess you really don't want it, since you keep throwing it away. I certainly won't go get it for you again."
I've had three bassets. They were all extremely smart, very sneaky, kind of tricky. And none of them played by fetching.
