    Squeaker short-lived, enjoyment long-lasting
    Size: Large, Color: 5 Pack
    My 10-pound dorkie rips out the squeakers in about 30 minutes. I wish they were sturdier or the parts of the toy housing the squeaker were reinforced. However, he is so excited to get a new one and will continue to play with it even when the squeaker is out. He loves to play tug. They do get pretty gross from the chewing and definitely benefit from a trip through the washer. While this is not a very sturdy toy it provides so much entertainment I had to give it four stars.

    Husky Approved
    Size: Large, Color: 5 Pack
    Okay, so my husky, bless his cotton socks, thinks he's a furry little demolition crew. Usually, plush toys last about five minutes before they're disemboweled, leaving a fluffy white crime scene all over my living room. BUT! These Sharlovy toys are a game changer! They're stuffing-free, which is a HUGE win for my sanity (and my vacuum cleaner). He can happily gnaw away, trying to get to that squeaker (and succeeding, eventually, because, husky), but without the usual explosion of fluff. Five stars for saving me from a lifetime of stuffing-related stress. If you have a chewer, give these a try. Your house (and your head) will thank you.

    No Mess, Lots of Fun!
    Size: Large, Color: 5 Pack
    My dog absolutely loves these toys! The squeakers and crinkle sounds keep him entertained for hours, and I appreciate that they have no stuffing—so no messy cleanup when he plays a little rough. The variety pack is great because it gives him different animals to choose from, and the toys are surprisingly durable even with lots of chewing. They’re lightweight, easy for him to carry around, and perfect for playtime or keeping him busy when I’m working. Definitely a great value for the price, and I’ll be buying again when he wears them out. Highly recommend!
