Designed for you, the performance enthusiast, Comp Cams DynoSim Advanced simulators have unmatched power to find the best component combinations for any engine project. Here's how the DynoSims work: Horsepower is determined from an analysis and integration of cylinder pressures from 2,000 to 11,000 rpm. All basic engine components and specifications are accurately modeled, including 1-to-12 cylinders, a wide range of cylinder heads and port configurations, naturally-aspirated and forced-induction systems, airflow, and virtually any camshaft timing or valve lift. ProTools allow viewing, graphing, and printing "technical" engine data, including engine pressures (imep, bmep, fmep, pmep), power loss from friction, volumetric efficiency, and manifold vacuum at each power point within the dyno test. Use this data to gain a deeper insight into engine operation and efficiency.

Finally, a sturdy oversized ball my boy can't destroy! And can pick up easily
This is just wonderful! My dog has destroyed all other balls! I think this is finally one he cannot destroy. And I love the holes so he can pick it up and throw it himself. LOL. And it BOUNCES, bringing him endless joy and skill in catching it. Cause you don't know which way it will bounce off the ground. Oversize was just right for him. Glad to have found this great sturdy ball.

Almost perfect...upraised logo should be left off
This toy is great for relentless chewers with strong jaws! It would be almost perfect if it didn't have a "K9" logo in raised rubber on it. That is the place that my aggressive chewer shepherd/bulldog mix focuses on and is able to get small chunks off. Without that logo, he would chew the ball more evenly, instead of fixating on that one spot. He loves this ball and has chewed on it for about an hour off & on each of the 11 days he has had it. Although it is very durable so far, the flaw is the upraised logo.

Perfect for High-Drive Dogs & Surprisingly Durable (six month review)
I use this ring ball for structured fetch and tug sessions with my high-drive German Shepherd mix (91 lbs. at 10 mon.), and it’s easily the best toy we’ve added to our routine. What makes it truly exceptional is how it allows my dog to engage in the full canine predatory sequence:
• Chase: He locks in visually and bolts after the ring when I throw it.
• Grab & Hold: He brings it back, pins it against my leg, and bites down firmly (the toy—not the leg!)—his way of acting out the natural catch-and-control behavior.
• Unalive & Tug: We finish with a strong tug session, which satisfies his instinct to grip and shake—basically his version of “making the toy unalive.”
• Settle & Chew: Afterward, he relaxes with a chew toy or eats—completing the full physical and mental cycle in a healthy, balanced way.
Durability is outstanding—this toy stands up to intense tug sessions with no tearing or damage, even with a 91 lb powerhouse. My senior dog also joins in for double tug play, and it holds up beautifully to that too.
I don’t leave this toy down for chewing—it’s not a chew toy. I use it specifically for fetch and tug, then put it away when we’re done. This keeps it exciting and extends its lifespan. My dog has other chew toys he can use freely throughout the day.
This isn’t just another fetch toy—when thoughtful it provides a structured, instinct-satisfying experience that’s mentally enriching and physically engaging. If you have a high-drive or working breed, or a dog who thrives on interactive play, this ring ball is 100% worth it.

Unpredictable bounces
Size: Small, Size: Small
My 3-year old Cavapoo loves these little toys, although I haven’t given them to her all at once. Typically, she is able to chew a little hole in anything with a squeaker within hours. The first one I gave her, it took her more than a day to chew off a little ear, but she still love to play with it. The second one is completely intact after more than a week. What both of us like is that the shapes with tiny nubs make the toys bounce unpredictably. They are small and light-weight which makes them easy to throw in the house without doing any damage. I am careful to not throw them at the TV or delicate items. I’ll actually buy them again when she needs more toys.
EDIT 3/19/2026: It’s 3.5 months since I first wrote about these toys. Tater is playing with all four critters. It’s a miracle that all of them are intact and squeaking! Even the one with an ear missing squeaks as long as I cover the little hole. I just added all of the Chiwawa toys to favorites so I can find them again—if or when these ever wear out.

Fun Bath Toy - Loud Squeaker
Size: Small
My dog loves these little squeaky toys. The squeaker is loud and the toy is very durable. She can chew on it and it still looks the same. We love to add them into the bathtub when it’s time for a bath to make her less stressed. She loves to bat them around the house. They roll around pretty well.
