If you have dogs that like to play fetch, these are a must have!
Color: Orange - Pink, Size: 2.0"(Small)-4 Pack
My pups love these sp much, they won't play with any balls other than these. Not sure if it's the small size, or the fact that they squeek, but they def were a hit.

Fun balls for a small doggie
Our little Cockapoo loves these balls. When she can’t entice us to play, she has figured out how to bounce and chase a ball by herself - very cute!

Great for my aggressive chewers
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
Wears my Labs out. Fred the yellow lab chooses this pig ear over all his nyla and natural chews out of the toy box all the time. This is the 4th one in his 6 years. They have lasted long and when new are large enough I don’t have to worry about choking. As they get down in size I throw them just as a precaution. The only con I can think of is Fred loves to slam it down on the pergola floor which makes for a very loud clacky sound and it scares the $%^ out of me. He of course thinks it’s funny so he picks it up and continues to do it. As long as he and his brother Willie can chew I will always have these in their toy box.

Great chew toy for large, tough chewers
Size: 1 Count (Pack of 1)
My dog is a heavy, strong chewer over 100 lbs who will chew this for an hour. It lasts, keeps him occupied and the smell isn’t terrible. Love the large size for a larger dog. Great buy.
