Good for Teething puppies
Color: Teething Stick
After getting my fingers chewed and bitten by my new foster - 8 week old Yorkie , I was desperate to find good teething toys. Fortunately this one arrived quickly. Turned out to be very good for teething puppies! Charlie loves this cooling stick. Once it’s frozen, the cold really seems to soothe his sore gums. The icy part doesn’t stay frozen for long, but it works so well that I bought a second one to keep ready in the freezer while he’s working on the first.
Even after it warmed up, he still enjoyed chewing on the soft stuffed part and the tentacles. The product card says not to use it as a chew toy, so supervision is a must, but it held up just fine so far.
Overall, this has been a big help during the teething phase — short-lived when frozen, but very effective while it lasts! And worth every penny to save my fingers from being a chew toy.

Chicken flavor mild kinda just taste spicy plastic but flaverfade quickly. It off-white more than white but it look mostly like picture otherwise. hard and durable but nit hurt teeth. Medium suggested for average human.

Tough Chewer Approved but Not a Forever Toy
Flavor Name: Original, Size: X-Large
I do like this toy for what it is meant to do. It is definitely built for strong chewers and holds up way better than softer toys that get destroyed in minutes. The texture keeps dogs interested and gives them something to really work on, which helps with boredom and can support dental cleaning through chewing. It is one of those “finally something that lasts a bit” kind of toys for heavy chewers.
That said, it is not something you just toss in and forget about forever. Like most hard nylon toys, it will wear down over time and should be checked regularly for rough edges or changes in shape. Some dogs will also go through it faster depending on how intense their chewing style is, so replacement will eventually be needed. Girl, this is one of those “it survives the chaos better than most, but you still need to keep an eye on it” situations.
