No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

My dog like this!
Size: Small, Style: Mutts & Mongrels
My dog likes to play with this but I think she would like it better if the squeaker was larger.

Don't buy it for your dog.
Size: Medium, Style: Sour Pooch
This was in the trash 10 minutes after it was opened. It is not durable. Better as a cat toy.

RainboW Latex Dog Toy
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
The size was a good fit for my wire haired fox terrier, Gady. Quality: colorful, durable, Gady could grab it anywhere and shake it and make it squeak. Squeaking was her best joy. I recommend this Fringe Studio dog toy.

Cute but not durable
Color: Life's A Paw-Ty, Size: 4.75" H X 5.25" W X 2" D
Beautiful toy and super fun squeaker, my dog loved it so much, unfortunately, it didn't even last 30 minutes! My dog is not an aggressive chewer but the material is very fragile and she made a whole right away.
