My dogs go CRAZY for these!
Color: Ring
My Pitbull and Frenchie go CRAZY for these! They do have a leathery type smell to them if you’re sensitive to that (doesn’t bother me) and my dogs WILL ingest what they tear off if I don’t watch them closely. Only removing 1 star because of how fast my dogs tear these apart and how deliciously enticing they apparently are to ingest, but my dogs may just be psychopaths. :)

Not the most durable, but my dog LOVES it.
Style: Plush Surprise Color, Size: 24"
My boyfriend’s dog had the small version from Petsmart and she has been very gentle with it since she likes it so much. I decided to surprise her with this 24 inch one for Christmas. She was obsessed! It’s cute, it’s very soft, and has a big squeaker in the top, which she loves! She was a little more tough on it and it did get some rips 12 hours in, but it is still in one piece at the moment and brings lots of joy. The dog is a medium/large size.
Dog toys can be so expensive. I personally think the was a great price despite not being the most durable. I may purchase again next year!

Update: Excellent Customer Service Made Everything Worthwhile!
Style: Plush Surprise Color, Size: 24", Style: Plush Surprise Color, Size: 24"
07/17/2025: This doggy toy was destroyed within 2 hours of its arrival. In my opinion, it was not at all worth the cost. (1 star)
Update (07/19/2025): I have contacted the manufacturer and they said they will send out a new replacement toy.
As of now, I have revised the review to 2 stars for the excellent and efficient customer service pending arrival of said replacement. Will update again soon. (2 stars)
Update (07/23/2025):
The replacements have arrived! My dog loves the new plushie sloth and so far it is in tact. It doesn't have stuffing in the body as far as I can tell, so little to no clean up hopefully. They also sent her a spiked squeaky ball and she's getting used to it. This company has some of the best customer service and support that I've experienced. (5 stars)
