My greyhound mix poops a certain way everytime she does it. She has never pooped outside so I see her do it twice a day in my living room! (Thank God for hardwood floors!) Her routine is poop, walk away and kick her feet back like burying it, turn and sniff her butt while doing a couple of circles, then she walks back to the poop and smells it, then goes on with her day as normal. Well today, she did everything as normal until she sniffed her butt, when her nose got there she jumped straight up into the air, sneezed, ran to the poop smelled it, ran very fast to one of my other dogs, sniffed his butt, then ran back to her poop and smelled it. Then came over to me with a confused look on her face! It was one of the worst smelling poops I have ever smelled come from any human or non human! Thats probably why she acted the way she did!
