For example, the writing on one "pet" tennis ball contains 2,696 ppm of lead and 262 ppm of arsenic, a proven human carcinogen. There was no lead in any of the "sports" tennis balls tested. However, there was small amounts of other metals including antimony, bismuth, cadmium, chromium, copper, iron, magnesium, mercury, nickel, silver, and zinc.
Therefore, throwing or giving your dog a used tennis ball could be harmful to him/her, even if it appears to be new.
Lead is known to be toxic to humans and animals. Even at low levels of exposure, it can have negative effects on the brain, kidney, liver, immune system, and reproductive organs. Arsenic is also a toxin that can be found in natural gas wells and coal mines. It can cause skin lesions, headaches, diarrhea, abdominal pain, shortness of breath, and heart problems. The only way to be sure whether a ball has contained toxins before it was thrown or played with by your dog is to check its core. If the core is still solid then the ball was not exposed to toxins previously. If the core is soft then the ball had exposure to toxins previously.
The best thing you can do for your dog is take care of his health and well-being first and foremost.
Even before the tiny fragments of rubber reach the animal's intestines, chewing on tennis balls can cause enamel erosion and represent a choking threat. "It is very likely that a tennis ball includes lead, as well as a plethora of other harmful elements," says Animal Dental Care. Lead is toxic to animals in any form, even if it is not visible. Chewing on objects containing lead can cause brain damage, kidney failure, and death.
If your dog has access to a yard, this is an opportunity for him to play fetch or tug-of-war. The exercise is good for both you and your dog; playing games together helps us socialize and have fun. Avoid giving your dog too many balls all at once so he does not become bored or end up throwing them out instead of playing with them.
If you take away his ability to use his teeth, he will either fight or submit. This means you should only give your dog soft toys or old socks to chew on instead, as these items won't put him in danger of breaking the law or hurting himself.
Your local pet store should have varieties of toys available that are safe for dogs to chew. These can include simple rope toys or more sophisticated laser-light systems that provide different levels of difficulty. If your dog likes to chew things like shoes or furniture, then he will probably enjoy having tennis balls as well.
A Reddit user made a public plea to fellow dog owners by uploading a photo of her post-surgery dog (see below). Tennis ball parts, glue, and fluff had been chewed up and consumed by the dog. They were able to preserve her life, thankfully. So, while it is obvious that tennis balls may be extremely harmful, are they genuinely toxic?
They are designed to be low-cost leisure balls for the sport of tennis. As a result, many compounds are employed as components, some of which have shown to be quite dangerous. The problem is that there is no means of knowing which ones.
The topic has been debated at length, and now UN officials have concluded that ping-pong balls should no longer be categorized as hazardous items. Fortunately, the International Table Tennis Federation mandates that all balls used in official matches weigh 2.7g....
Balls may be lethal if they are too little for the dog to play with. Golf balls are especially dangerous since the liquid inside is frequently poisonous; if your dog manages to penetrate the outer layer with her teeth, she might get extremely ill. The best course of action is to keep your dog away from golf courses.
Golf balls are not designed as toys for dogs, but rather as exercises for humans. If you take away this purpose, then yes, they can become deadly if your dog swallows one. Most dogs who swallow a ball of any kind will pass it along with some water, which should be offered immediately in case of choking or obstruction.
If you see your dog with a golf ball, remove it immediately so that you do not add stress to an already anxious situation. Call your veterinarian right away if you observe signs of pain or illness after you have played a game of golf.
