Cute but not durable
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
Beautiful toy and super fun squeaker, my dog loved it so much, unfortunately, it didn't even last 30 minutes! My dog is not an aggressive chewer but the material is very fragile and she made a whole right away.

Not as advertised
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
Purchased this product under the description for tough chewer. Description even showed a husky in which I have 2. Needless to say, the toy literally lasted 2 minutes before it was destroyed and was full of a fiberglass fiber. Would not recommend this toy if you have a larger dog with a stronger bite force.

My Dog's All-Time Favorite Toy
Color: Pink, Style: Grunt Sound
The first one of these I ever got her was at Petco on sale for $1 - best $1 ever! The reviews are right, though. The toy doesn't last forever and it's not good for aggressive chewers. In my opinion, however, that doesn't make it a bad toy. Here's why: Aggressive chewers comments: Getting my sister's French Bulldog a stuffed toy (that's shredded in 5 minutes), compared to my Pitbull who does not tear up any toys, but is a stronger chewer when it comes to bones. My pup does not tear this up at all, but my sister's dog would. My point is: Don't get your dog a soft toy if your dog ruins soft toys. Regarding the not long-lasting comments: the honking noise mechanism inside eventually pops inside the hole, rendering it honkless. Ours lasted about 6 months. It's pretty much impossible to fix unless you want to trouble yourself to fix it for 1 good honk each fix. I would, but I do also have a job to get to. My dog does still carry it around in it's noiseless state, but she doesn't play with it with the same enthusiasm. How did I resolve this? I bought her 5 😂 She's only on her second, but I decided to stock it because they were on sale for $5.10 - I don't think I will get rid of any of them. I will just let her play with them on rotation until they fall apart. Besides all that, my dog just simply loves this toy. I have never seen her so happy & playful with a toy. I can't promise this for your dog, as I can only tell you about mine. We even have a "Sheepy" song. [I have not been paid or given free Sheeps - my Sweet Pea just really loves her Sheepy]

Loud! Just Like She Likes It
Color: Hedgehog, Style: Big Squeak Hedgehog
My Great Dane loves this noisy toy. She prefers squeaky toys with loud, unusual squeakers. (I need to invest in earplugs.) She's not an agressuve chewer or rough player so this should last a long time. Like most squeaky toys she has, the squeaker wears out before the physical toy does and once the noise is gone she won't play with it any more. If others have a similar issue...check with your local animal shelter. Some (not all) will disinfect used toys for the dogs in their care.
