Durable, fun, and good for aggressive chewers
Color: grass-green
I have bought this toy for my dog twice now, and the first time I purchased it, it quickly became his favorite. Unfortunately, I lost the first one when some other dogs took it down the street while we were playing outside. It was a bit heartbreaking to lose it, but after about two weeks, we managed to find the old one. However, it was in the middle of the street and had been run over several times, resulting in a broken squeaker. Despite its rough condition, it was clear how much my dog loved that toy. When I bought the new one, I was relieved to see that he doesn’t let it out of his sight at all. We have so much fun together, playing with it by throwing it in lakes, sandy areas, and engaging with other dogs. Even after all this rough play, the new toy is still intact. My dog particularly enjoys the squeaker feature, which adds to his excitement during playtime. He is an aggressive chewer, but this toy has proven to be more durable and has lasted us much longer than most of the other toys we've tried. It has definitely become a staple in our playtime routine!
