Nothing Great & Not Long Lasting
Style: 6 Piece Discovery Set 2, Style: 6 Piece Discovery Set 2
Ordered this sample set to see which scent I liked best before committing to a whole bottle. Honestly none of them were a favorite or a scent I would want a whole bottle of. I liked the 11 11 out of all of them. The Midnight was the worst and I felt like it didn't fit the rest of the scents, it was very strong. I also wouldn't order any of these because the scent is not long lasting, or atleast it isn't on me.

Belgian Malinois approved
Size: Large
This ball was the perfect choice for my 8 month old Belgian Malinois. Should last for years so far it has survived all her chewing needs. It’s the perfect size so I don’t have to worry about her swallowing it.

Good chew toy for an aggressive chewing dog
Size: Large
Well built for an aggressive chewing dog. I wouldn't say indescribable but it has lasted longer than all other chew toys he's had.
