This 4th of July weekend, if you see a tennis ball on the ground, think twice about picking it up.
A popular firework idea making its rounds if the homemade tennis ball firecracker.
While illegal, it can also be very dangerous for you and your pet, especially since dogs love to play fetch and are more likely to approach an abandoned tennis ball they see on the street.
If one of these goes off it can cause severe damage to both of you – ripping off a hand or an arm or exploding in your dogs mouth.
So before picking one up and/or throwing them for your dog, check to make sure its safe.
Warning signs include broken seams, cut marks, and something sticking out of the ball.
Or better yet, just leave it alone!
