Great Variety for Teething Puppies, Keeps Him Busy!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
I got this 9-pack toy set for my 11 lb chihuahua-terrier mix puppy, and it’s been very well received by my little guy. He’s been bored being in quarantine until his vaccines kick in and he's also teething. This toy set has made a huge difference. Great variety - you get a combination of rope toys, plush squeaky toys, and even a treat ball, so he often rotates between them depending on what he wants. The rope toys have been especially good for teething, while the softer toys keep him entertained. One of the plush toys has that crinkly texture inside, which he loves. The treat ball is a nice bonus too. I've put treats and his dog kibble in there throughout the day, and it helps keep him engaged and also mentally tires him out. Everything is sized well for a small puppy and light enough for him to carry around easily. The materials feel decent for the price, especially considering how many toys you get. That said, I do keep an eye on him with the softer ones since he’s still a puppy and likes to chew. Pros: Good mix of rope, plush, and interactive toys Great for teething and keeping him occupied Treat ball adds a mental challenge Good size for small dogs/puppies Nice value for the number of toys Cons: Softer toys may wear down faster with heavier chewing Overall, this has been a really useful set during a phase where he’s both teething and needs a lot of mental stimulation. I’d recommend it for small dogs or puppies, especially if you want a variety instead of buying individual toys.

Perfect Puppy Starter Toy Set
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
This toy pack is such a great value for puppies. My puppy stayed entertained for hours and loved having different textures to chew and play with. The toys feel soft but still durable enough for everyday use. A few of the smaller toys are better for light chewing, but overall it’s a fun variety pack for keeping a puppy happy and active.

Very small toys! But they are fun!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
All the toys in this pack are very small. I almost sent it back because I was worried they’d be too small for our new puppy. I’m glad we didn’t though because she loves all the toys. Her favorite is the fox because it makes the crunchy plastic sound. She will outgrow the toys but for now this was perfect for her.

Great Toy Bundle
Color: 9 Pack (No-stuffed Fox)
My puppy loves these so much that I purchased a second set! The toys keep him engaged, are very cute and soft, and so far have withstood the wrath of a slightly psychotic furchild! Highly recommend!
