Highly recommend
Color: Black Green, Size: 8 Inch
I was skeptical that it would hold up to our aggressive chewer puppy (staffyX) - especially during teething. But it has survived past teething into adult chompers and is still fantastic! Its his favorite outside toy, especially the tags make it fun (and those have been holding up well too). If/when it fails, I'll buy another one.

great design, poor overall quality
Color: Black Green, Size: 8 Inch
My dog loves these balls. The "tags" are a great design. The problem I have is the quality as they aren't tough enough. He goes through them pretty quickly tearing off the tags and puncturing the ball. He doesn't get that these actually cost money!
Each one also comes with a small pump, which I guess is great for a one time buy?, but man, if you don't own a pump just buy one and keep one. I have no use for several of these cheap pumps. How about offering the pump as an add-on for a dollar or two?

Ummmm🙄 not indestructible!
Color: Yellow Green, Size: 6 Inch, Color: Yellow Green, Size: 6 Inch
I have a Aussie doodle ( 1 1/2 yr old) so I decided to get her this one for Christmas and she loved it (she plays soccer with my grandkids-so I thought it would be a perfect gift and the colors are so cool green and yellow) however ..if your dog is like mine, she busted it within two days first tried chewing off the handles so I decided to cut the rest of them off-then proceeded to tear one of the pentagons entirely off and finally completely busted it… which made her very happy, but I was very sad!! If your dog is not a chewer and does not stop until she tears it apart, especially if it has some kind of noise maker which this does not-it’s a great ball and really well made! She loved it from the minute she got it played with it-wouldn’t let us take it away from her!
It is made and looks like a real soccer ball. So I will have to keep searching for an indestructible soccer ball🙄😁

My dog loves this.
Color: Black Green, Size: 6 Inch, Color: Black Green, Size: 6 Inch
I have a large Cane Corso who could obviously shred this but, she loves it. This ball is holding up really well. We use it for outside play and she loves batting it around and swinging it from the loops.

What a wonderful treat, loved by our very fussy dog!
Our very fussy Havanese absolutely LOVES these sticks! I had to find a new product after the USA-made chicken wrapped rawhide sticks were no longer available. It is very difficult to find a quality product made in the USA & while these are made in Cambodia, they seem to be made under very strict standards. I was also impressed that this co. claims it has never had a recall of their products. I also relied on the many, many excellent reviews of past customers. Our Teddy gets a stick every morning & then will wait by the pantry to get an additional 1 or 2 or more throughout the day! He usually does not eat the rawhide, just chews it up a bit. He is in love with these!! He also has a sensitive stomach & these have never bothered him one bit. His teeth are also quite clean from using these!
