Great inside toy
Theme: Football, Size: Large
Our Rottie loves these! I wanted something like the Jolly Ball but that is soft for inside the house. She's had a lot of fun with this, picking it up, tossing it, playing soccer, etc.

A BIG hit with my BIG dog!
Theme: Football, Size: Large
My Great Dane/Boxer mix LOVES this toy. She is over 100 lbs and very strong. She got a hold of my son's real football last year and after she made the initial holes and deflated it we just let her have it. She completely ripped it to shreds in about 7 months but had such a blast tossing it around and galloping around the yard with it, I knew I had to replace it with something of the same shape but hopefully more durable. This is it! She really adores this. We play catch and tug with it and it seems like it's going to last a really long time. The rubber is flexible but strong. I'll try to get a picture of her with it and load it. I highly recommend this toy. We ordered the Large size, by the way. :-) 2-6-2015 - Update: I am just now ordering a new one. For nearly 4 years, the old one has been kept outside in the rain, sun, snow, and ice. She still loves to grab it, shake it, throw it up in the air and play tug with whenever she's outside. The rubber is just now starting to crack so it's time for a new one.

Holding up very well, favorite
Theme: Football, Size: Large, Theme: Football, Size: Large
A few weeks ago I ordered three dog toys for my dogs. I have a German shepherd, Lab mix and a medium mix. The latter boy is the biggest destroyer in our family, he chewed pieces of a black Kong. I did not really have high hopes for this football shaped toy with holes, but it is holding up beyond my expectations. You can see some teeth marks, but they are not chewing it up (yet?). They love to play tug with this, kick it around by themselves, or lie down with it and chew on it. I like it because it is a soft rubber and doesn't make so much noise when they throw it around on my hard flooring. For the price, they are definitely getting a whole lot of fun out of it. Edit: Now, more than a month later, my dog managed to get a small piece off after a heavy chew session. After that first piece apparently it is easy to get more off, and he wants to swallow it so the ball is in the trash.

dog's ball
Theme: Football, Size: Large
Was too big and very heavy. Smaller would be good for my very large full male german shepherd. But he loves it. Too heave for smaller dog.
