Fun game doesn't last

My daughter asked Santa for the Doggy Doo game. Christmas day we play it & find out at 3 she isn't strong enough to push the handle on the leash (that pushes the poop pellet through the dog with air). Game is for 4 & older so oh well, she spins, we squeeze the handle! She has now had it 10 months, played maybe 30-40 times & it broke. The leash doesn't pump enough air now & it takes forever to push the pellet through. What used to take 4-10 squeezes now can take up to 30 squeezes. Won't buy again as it was $22!
