Can someone point me to the artical about the tennis balls being bad for the dogs teeth? I keep searching but cant locate it.
P.S. For some strange reason most people i inform of it kinda doubt or question how truthfull it is, dont know why? the last person asked me in what medical journal the study was publised in. all i could say is that it was done in Germany. so does anyone know where it was?
Also, Ed if you see this, is it ok to print it & post it on a board for peoples information?
Gerlert's master, returned to find his son gone & his crib bathed in blood. Seeing Gerlert's bloody mouth he stabbed and killed the dog. The noise woke the baby,hidden in the blankets. Under the bed,was a dead wolf. It's throat had been torn out.

I"ve used tennis balls for years and have never had a problem. The dogs are not permitted to keep them, they are used only for rewarding proper behavior. I'd be concerned about letting a dog keep one, as they can burst, be swallowed and become a choking hazard.
I've never seen a problem with teeth however, and that is over 35 years of using them on literally thousands of dogs.

Any behavior that is reinforced is more likely to occur again.
FYI: The issue was: that the glue used to clue the felt on the tennis balls created some kind of chemical reaction with the dogs saliva & that in turn would eat away at the enaml. If i remember correctly.

I've heard of the chemical reaction of the glue/saliva/enamel as well.
For those who want to know the detailed makeup of a tennis ball:
Tennis balls are made of a layer of rubber surrounding a hollow center. They are comprised of 2-piece rubber cores that are
cemented together. The seams between the two pieces of the core are exposed, but covered with elastic sealant. Then they put a thin layer of adhesive on the rubber and cover it with a layer of synthetic felt (real felt is made from wool). The letters that you may see on the felt are just black ink. The air pressure inside the ball is 12 psi (pounds per square inch) greater than ambient air pressure
at sea level (the 'normal' air pressure all around you). The ambient air pressure is 14.7 psi, so all together, the pressure inside the ball is 26.7 psi.
I'll take a guess that the glue used is a chemical base glue since they use a synthetic felt. I don't have the German study, but common
sense says there would be ill effects to carrying around a soggy wet ball covered in abrasive material and chemical based glue in
your mouth.
