    zelda‘s “indoor” ⚽️ ball!
    Color: Squeaky Green, Size: Medium Size 2 (6")
    zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed. it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!

    Small for a medium
    Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
    I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

    Great toy for a GSD
    Color: Blue Gray, Size: Extra Large Size 5 (9")
    My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

    Perfect for my dog
    Color: Blue Puppy, Size: Medium Size 2
    My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!

    Pup loves this!
    Color: Blue Puppy, Size: Medium Size 2
    My pup loves his soccer balls. These are very durable although if you have a dog that doesn't grasp the concept of using the loops/straps to carry it, teeth could puncture it. They are a good value for the money if your dog likes to chase the ball, I get the smaller size ball for my dog (medium dog). They come with a pump but if you have a bicycle pump or a battery operated pump, it will fill much faster. Ours stay outside and even in the winter, they hold up well, just need a bit more air occasionally to keep it pumped up.
