Question: are they made in the USA?
Document: I agree with a previous reviewer these tennis balls will hold up to bigger dogs. My 2 rotties can play with them along withe chiweenie and yorkie. Yes they all get along :)The balls do hv a funny smell to them, chalk it up to "made in china"
They work fine as dog and cat toys, which was their intended use. Reasonably priced, but I would have preferred to have been provided with 18 tennis balls as stated in the description, not the 17 that I ended up with.
There are two types of people looking for tennis balls: tennis players and dancers. This review is geared towards the second. Now, if you're new to dancing you may not know about rolling out. It's time to learn. Rolling out means giving yourself a deep tissue massage using your body weight to provide pressure. It helps break up knots in your muscle tissue that stretching won't fix. You want a variety of rolling tools. Foam rollers, softballs, tennis balls, baseballs and golf balls.
The adjustment to these balls is brutal so far. I would recommend anyone who is trying to improve their game to keep looking. The bag is nice and I do like the not so common brand name, these balls do not get mixed up at public courts.
Tennis balls are medium sized and soft. They are the defacto ball to start with to help roll out backs, shoulders, hips and the bellies of your muscles. This 18 Ball Pack is about $15 so you're paying about $0.80 per ball. You'll have a few to stuff in all of your bags and a few extra to replace the ones you lose.
My young lab puppy loves to chase tennis balls, but I didn't want to buy the expensive ones. When I saw these and the comments, I thought this will be perfect, 18 balls for a very reasonable price. I've already thrown out a few (she tore them up very easily) and I just got them last week. They are not as durable as I hoped, or maybe my dog is just too hard on them! She loves chewing on them when I'm not throwing them to her.
My son plays tennis and we like to hit balls back and forth to each other. So I bought this bag of balls with the idea that we would both have plenty of balls with us at all times. It is frustrating to have just a few tennis balls and have to chase them down after each play, so this was well worth the rather inexpensive investment.
My dog loves playing fetch with these tennis balls. She chews on them a lot and they hold up really well! I bought a bag of 18 and it lasted me over a year. Buying again!
My dog is obsessed with tennis balls and these are a fabulous price for quality, bouncy balls. She loves them so much we have to hide them until we're ready to play fetch outside.
I was sceptical since Wilson, Penn and Dunlop are your big time brands. But the price was right, so I gave it a try. I found the bounce to be excellent ... like the regular tennis ball. I tried the balls in my electric ball throwing machine. The felt held up quite well after being fired from the machine for a week. Since they worked for me and saved me money, I purchased the Tourna 50 pack in a carry pouch.
