While not the exact 1s I purchased previously, they appear to be the exact same type of squeaky tennis ball. If your dog is a destroyer of toys as mine is, you will want to make sure you don't leave the ball in their possession after finished playing with them. My corgi has a near 100% tendency to rip the outer fuzz layer off if left unsupervised with them. However, I still highly recommend them to anyone especially if they are overzealous in their attempts at catching the ball sometimes. With my corgi, she really gets into trying to catch the ball midair and sometimes isn't lined up perfectly causing the ball to get bounced off her snout pretty hard. With a more solid tennis ball, she may hurt herself, however, these ones will not cause any such harm which makes them perfect for her. Also, they are perfectly sized for smaller dogs as well, this way she doesn't struggle to catch them midair as she often can with larger toys/balls. So if you have a pooch that is small/medium-sized and loves to play fetch, this might be the perfect purchase for you and your doggo.
