The only plush toys that last for my girl!
These are awesome! I have a 4 year old doberman and she destroys most plush toys in a matter of minutes. These are the only ones that last and are worth the money! Even once she does pull the stuffing out, the shell of the toy is still mostly intact and she'll play with that for a long time as well!

Our doggies favorite toy
Color: Yellow, Color: Yellow
This is our 3 dog’s favorite toy! We’ve had it for over a year, it’s lived outside for a while, was buried, found, taken all around the house. This toy shows up in the most random places and is still in tack (for the most part). They fight over this toy. They also have the pig from the same brand and it’s still alive! Other toys are usually shredded in a few days.

Not a strong toy for chewers.
Color: Yellow
Not quite as strong as its description. My dog chewed off its foot within the first 10 minutes . I expected it to be stronger because it’s made of Kevlar material but it’s not that durable. Save your money it is far from being durable / indestructible.

Soccer ball just for dogs
Size: 6 Inch Diameter, Color: Ocean Blue
I could say "soccer", and our shoodle would wag her tail ready to play soccer with a tennis ball so I tried out this real soccer ball with her. Mostly, she just wants to wait for me to kick it, playing defense, so she can chase it like the tennis ball. After that she wants to usually bite it or roll over on top of it as a way to secure the ball, but sometimes she will have fun pushing it around with her nose or paws. She still prefers the frisbee for play time outside since the frisbee is good for catching and for playing tug-o-war, but this is a good alternative that always gets her wagging with excitement.
I wanted to get a regular 6" soccer ball for our shoodle, but this was a good choice for dogs for the durability and safety of the rubber material. The hexagons give the dog some grip to pick it up. The rubber is soft enough to grip and expel air when they do figure out how to grip it. The ball is designed to suck back in air when the dog releases the ball.
- Durable rubber material ideal for dogs
- Dog can squeeze out air to grip it
- Ball fills back up with air after air is squeezed out
- Can make more noise than a leather soccer ball
- Noise is still tolerable when used indoors
