LOYEE 8‑Pack Puppy Toys — Cheap, Tough, and My Pup Loves ’Em
Style: 8 - Pack Frog
I grabbed these LOYEE toys because my little teacup dog needed something to chew when the boys are loud and I’m making lunches. For the price they’re surprisingly durable — survived a few rough play sessions without falling apart — and the different shapes keep her interested so she’s not chewing shoes. They’re soft enough that the twins can toss them without hurting the pup, and washing them is easy when they get drool or dirt on them. If you need an inexpensive pack to keep a small dog entertained and not chewing up your tools or kids’ stuff, these do the job.

Highly recommend!
Style: 8 - Pack Frog, Style: 8 - Pack Frog
All the plush type toys and the frog have a great squeak toy in them that isn't too loud like most!! All are a decent size and have kept my girl entertained since I opened the package!! Love that they are bright and vibrant colors and seem to be very good quality!! My 9lh Chihuahua for size reference 😂 actually she wouldn't stop trying to steal them when I was taking the pictures lol. She especially loves the big frog and ball that you can put snacks into! The red bone seems to be a very hard durable plastic so she won't be able to chew it Into small pieces and choke, so very safe!
