Wanted to keep this for myself! Made well, size is perfect for a 90 pound pup, durable enough for a non chewer (she cleans their fur but doesn’t chew anymore). Durable enough that has been left outside during Summer storms and washed/dryed a couple times already (I use a laundry bag) and still has its adorable shape. Great value for the money, though I might need to buy another one for myself! *^_^*

Our Doodle's Fav Toy

Color: Multicolor

The first slothicorn toy that we received had a broken squeaker. We were able to quickly and easily get a replacement and send the broken one back. This is one of my pup's favorite toys, although I don't think the horn will last long-- it's the part she likes to chew on the most! At 5lbs, the toy is the same size as my Goldendoodle puppy. I think the toy is overpriced when not on sale (I got on Black Friday promo), so I would encourage waiting for a price drop before purchasing or locating another option that's affordable.

Not very durable if your dog likes to play aggressively with his toys.

Color: Shello There

My yorkie loves it. However he removed the rope tail tail on day one. Within a couple of days it came loose at the seem from chewing and he started pulling the stuffing out. I won't give back to him until I am able to mend it.

Puppy Crack!

Color: Pollen for You

Because its her only toy that crackels and the daisy (as in DaisyMae) flower moves up and down on the rope. DaisyMae loves it! Bee squeaks, flower dont, both do crinkle. But if you have a jaws of life puppy always going for your feet, its a great leg workout too. Well buit rope is nice to place in between your toes. Great buy. Super cute! Win Win! Toys are on the smaller size, perfect for a baby puppy learning a squeaker toy. Maybe 6 to 8 inches each. A nice buy for 13bucks.

Our dogs favorite toy

Color: Multicolor

The slothicorn is our dogs FAVORITE toy. The rainbow coloring is so cute. She loves playing with the unicorn horn. The horn is starting to fall off, but it's lasted a while since this is her #1 choice to play with. Will order another when it finally needs to be replaced. 10/10.
