Due to their high quality and great customer service, I own all Monster K9 toys they have. We have a 2 year old Belgian Malinois that requires daily activities due to his breed. Thus, high-quality, low price toys are an absolute must.
We use this as our back up toy when his Frisbee is out of commission. If you throw this overhanded with your palm facing towards you and flick your wrist, it rolls AMAZINGLY on the ground. While our Malinois loves playing with it the most, all of our dogs love chasing it as speeds across the ground.
To top it off, once you're done with playtime, if you want to your dog have it for the rest of the afternoon, there's almost no chance they're going to destroy it. It's a very high-quality rubber that is very similar to the rubber used in reusable rubber firearm targets. When punctures or cuts are introduced, the rubber material instantly and naturally 'self-fills' the gaps so you can barely notice it's even there. This dramatically reduces the chance of open gashes, spaces, or weak points for your dog to grab a hold of to rip it apart.
We've owned ours for 5 months now and haven't had to replace it. For $13 plus free shipping, this puts other "tough" dog toys to shame.
