足で地面をかく行動は、野生の祖先たちが広大な縄張りを示す必要があった頃の名残です。人間の嗅覚腺が500万個なのに対し、犬はなんと1億2500万〜3億個も持っています—つまり、犬の嗅覚は私たちとは比較にならないほど優れています。犬の足にはフェロモンを分泌する腺があります。フェロモンとは動物同士のコミュニケーションを助ける化学的なシグナルのことで、土を数回後ろにかくことで、その化学物質が周囲やほかの犬の鼻へと広がります。犬の親戚にあたる動物たちが、毎日見回るには広すぎる縄張りを示し、守る必要があった時代には、この行動が役立っていたのでしょう。というのも、排泄物は乾くとにおいが薄れますが、犬の足から残るにおいはより長く続くからです。これは犬の祖先が大切な狩り場を守るだけでなく、繁殖可能な仲間を守ることにも役立っていたのかもしれません。
後ろ足で地面をかくのは、正常で破壊的ではない行動なので、愛犬の習慣を変えようとする必要はありません。むしろ気にすべきなのは、普段は足をこすっている愛犬が急にやめた場合だけです。行動の変化は、愛犬の動きを妨げる何かがあるサインであり、将来的により深刻な問題につながる可能性があります。一方で、愛犬がいつもどおりにしているなら、気をつけることはひとつだけです。後ろ足でシャッシャッとするのが終わってから排泄物を拾いましょう—そうしないと、土やもっとひどいものが顔に飛んでくるかもしれません。

My dog does it after he urinates or defecate. I don't mind so much in our yard, but when I walk him he does it every time he stops and makes his territory. He just doesn't want to stop and can be pretty destructive. He is 8 yo and has only started it about a year ago.
Sure she kicks her hind legs after bathroom use, but tonight out of no where she started kicking her hind legs running around inside home then lay down for few minutes then run around and doi it again. She doesn't seem to want go out for bm .. feeling puzzled
OK, but what if my dog does this even if he’s not eliminating? And will sometimes do it on hard enough surfaces, and long enough, to sometimes make his feet bleed? Also, he sometimes does it on backwards circles. I took video of it and showed it to my vet, and he said he’s never seen behavior like that.
It’s almost like it obsessive; like he zones out and does it until you physically stop him, then he just snaps out of it. He was a rescue straight off the street, so I don’t know his history. I suspect he may have either been born with a brain defect, or sustained a head injury that brought it on.
Any ideas?
My dog doing same thing and he started today
We have a little (pug x chihuahua?) rescue dog aged 11 months who scratches her hind feet on the floor when you talk to her or if another dog has a toy she wants - almost as a frustration release. She has neurological damage from untreated distemper as a pup which has left her hyperkinetic and I think is why she displays this unusual behaviour......
I love when my little Pomeranian does this! She does it when she is playing and getting Rowdy … she likes to do it when she wants something to like she wants to be the boss ! I love it so cute!
My shishon does this when she wants attention. That is the ONLY time she does this. She is tearing up my carpet because the force is so strong. But like I say the only time she does this is when I am on the computer, telephone or watching tv and she isn't getting attention, lol
