Toys For Puppies
Color: Multicolour20
This package is suited for puppies and it is priced right. 20 toys for 20 dollars and my little guy loves them. No outlet pet store will sell you this amount for the price. Great buy.

My puppy loves to pull the toys out of this box and he especially loves the rope he likes to chew on it and I just really like that there are different kinds of toys for him so he doesn't get bored. The rope only lasted a couple of months. He chewed the heck out of it.

Could be dangerous for smaller dogs
Color: Multicolour20
Most of the toys seem to be great, I have a yorkshire terrier and I noticed that on some of the toys that have small nubs and prices that he can focus on he is chewing off and eating which is not good for his little body so just be careful and pay attention to how they are using the toys so you don't end up at the vet with a problem you didn't expect

Great assortment at a low price!
Color: Multicolour20
Keeping a puppy engaged in toys can be rough but my puppy LOVES the assortment of toys that were included in this box! She is teething and the durability of the toys have held up well. The rubber materials are soft on her teeth and the rope toys appease her tug of war moments. Would 100% recommend for anyone looking for a good deal on toys.

Don’t leave your dog unsupervised with these!
Color: Multicolour20
Some of the toys I noticed break apart easily. I got these for my 4 month old puppy and they are definitely not chew resistant but he had so much fun playing with them. Some toys squeak. The toys are super cute but I don’t recommend letting your dog play with them without supervising because it can definitely be a choking hazard with how easily he tore them up. He normally doesn’t tear toys up easy so I won’t be buying again but he had fun with it while it lasted. Most toys had to be thrown away within 2-3 weeks.
