I made this for my size x Setter Spaniel
It is their absolute favorite toy, can be well cast but also shot.
First I've bought in a pet store. This held about 1 year, but was so brittle that he eventually lost air. However, since the ball was the whole day in the garden and thus was exposed to the sun, which is understandable.
The price I also okay if you look that many other toys (the one probably. Keep 1h) cost some more.
I will, if the current gives up the ghost, definitely buy again a :)
