Every Glamorous Pup Needs Pawfum
Color: Black Noir Pawfum, Size: One Size, Color: Black Noir Pawfum, Size: One Size
As a sophisticated young lady with impeccable taste, I can confidently say that the Chewnel Noir Pawfum is a must-have for every fashionable pup. The moment I got my paws on it, I knew it was special. It’s soft, adorable, and the perfect size for carrying around the house, chewing, cuddling, and showing off during my puppy playdates. It adds just the right amount of luxury to my toy collection. Not only does it look fabulous in photos, but it also keeps me entertained for hours. My humans can’t stop laughing every time they see me strutting around with my designer “pawfum.” If you’re a puppy who loves the finer things in life, this toy deserves a spot in your collection. Five paws from Pennie Lou! Because every glamorous girl needs her signature scent.

Will probably be destroyed soon, but SUPER CUTE!
Color: Pink Purse, Size: One Size
Super cute! It will probably eventually be ripped to shreds by my pups soon because it is not as sturdy as other toys out there. It is also pretty small so not the best for large dogs destructive dogs. My lab tries to eat it and rip it but my small chihuahua plays with it and fetches it (she also looks adorable holding it her mouth!!)
