My dog, Ruby, kicks up the grass after she pees and poops. But, my other dog, Lola doesn't. I always wondered what it meant and why.

They are both female, so sex can't be the reason. Is it because one is big and one is little? Maybe. I decided to find out.

Familyhandyman.com explains it like this,

.....only 10 percent of dogs will actually carry out this kind of behavior. This behavior is called “ground scratching,” and is a passed down trait from wolves and coyotes. In order for pack leaders to claim proper territory, they would use this behavior to set a boundary of where “not to cross the line.” Peeing in the spot doesn’t just sent the signal—spreading the dirt helps to draw that line.

I guess that's the reason they both act very different after they poop. Ruby is just special, (one of the 10% of scratchers) LOL
