So glad they found each other.

What an adorable little dog.

When you open a new can of tennis balls, you can get a whiff of thi particular odor. I don’t know how to describe it, but it’s quite noticeable and specific to tennis balls. I wonder whether that is safe for dogs. Humans, of course, don’t put tennis balls in their mouths. But dogs do, and is it safe for them? Just asking.

AI: Tennis balls are packed in cans under high-pressure gas (usually nitrogen or air) to maintain their bounce. The cans are sealed at about 12-14 psi higher than atmospheric pressure, which prevents the air inside the porous rubber balls from escaping until the can is opened. This pressurized packaging keeps them fresh and prevents them from going dead

...there will be someone on DU who knows all about it.

I would surmise that smell is because of the materials the tennis balls are made from. Just like that "new car smell" if from a combination of materials used in construction of the cars interior. As the plastics, leathers, trim, etc., outgas you slowly lose that aroma over time.

I used to take one of my doggos to the dog park and it was loaded with tennis balls. Tennis balls covered in the filthiest of everything imaginable!! The dogs didn't seem to care much!

I’m not crying 😭😭😭😭😭😭😭😭
