Why Do Dogs Roll in the Grass?
If your dog is anything like mine,she loves rolling around in a patch of grass whenever she gets a chance. And it always cracks me up to watch my dog,Nala,have the time of her life._1_ Is she cooling off? Is she just super happy? What could it be? Here are some of the most common explanations behind this behavior.
_2_ It’s important to remember how incredibly powerful your dog’s nose is. They are picking up on hundreds of subtle scents (气味)that we can’t even comprehend! Sometimes they want to enjoy a scent they’ve found in the grass and will roll around in it to do just that.
She’s cooling off._3_ It might even be a little wet from a sprinkler—the perfect place for your dog to cool off in.
She’s covering up her own scent. There’s another reason why your pup may be rolling around in that patch of grass. Some experts hold the view that dogs may roll around in the grass to cover their own scent._4_
She’s scratching an itch (痒).It’s good to rule out any allergies and make sure your dog isn’t rolling quickly to scratch a constantly itchy back or side,but otherwise,it’s probably normal that she’s having a good time.
_5_ I’m not sure about you,but now I’m even thinking about joining mine next time.
A.She’s having fun.
B.She’s enjoying a smell.
C.But I’ve always wondered why she actually does it.
D.If it’s a particularly hot day,the grass may look extra appealing to your dog.
E.It is not uncommon to see dogs rolling around in the grass at particular times of the year.
F.In other words,they want to smell like the environment so they don’t scare off prey (猎物).
G.If you notice your dog rolling around in the grass,it’s probably just her having the best time ever.
