Best toy ever
Color: Blue&Purple, Color: Blue&Purple
I have been through many many toys with my 4yo GWP. And she is not gentle with her toys. Normally a plush toy will last about a week before all stuffing is brutally removed and the squeaker is so worn out it resembles a limp noodle. Somehow, this toy has survived the last 3 months- squeaker still squeaking, no holes in the fabric, better yet there’s not stuffing to litter all over my floor for the vacuum to get stuck on! She loves this thing, she flings it around, tugs on it, catches it midair, loses it and finds it. Honestly 10/10. I wish I could buy stock in this toy.

Awesome toys my boys love!
Color: Blue&Purple
These are such a great value and my little dogs ADORE them! So far they aren’t chewed up, and they are super cute! They definitely love playing with them and I appreciate there not being stuffing all over. They love the crinkly legs and squeaker in the head.

GREAT TOYS FOR BIRDING DOGS.
Color: Blue&Purple&Orange
I would purchase these again!! These have lasted for the past four years with four dogs. My dogs love carrying these around and tossing them into the air. I have Vizslas, they are not heavy chewers, but love carrying toys in their mouths.

Worthless Dog Toy
Color: Blue
Buyer beware! This item is worthless - if I could rate it -5*, I would. It was delivered this morning and was destroyed literally within 10 minutes. The squeaker was punctured and two of the crinkle legs were stripped by my Shichon.
