we had the same problem with jazmine...my dane...it was snowing outside..then rained..so i was hard snow. Jazmine pooped on the snow, i picked it up...no poop on the snow aymore...i run inside and come out again and there are 5 piles of poop. I pick up after my pup...the other thing is that the poop that "jazmine" did...is the size of my ferrets poop. Now... i have a great dane...she poops LARGE... i got fined for me living with her because i swore i picked it up and i told them to test the poop for what food was eaten...so they fined me because i didn't pick up others poop. so i figured ok..you want to fine me for something that isn't mine...that is fine, but i will now contribute to the mounds out there then...i am payig for the removval anyway!! so i paid one month and let the poop build up...then the maintence guy came out and said...oh...yo ur dogs poop are a lot larger...... got my money back, and no more complaints after that one!!!! Tell them to test for the food that you feed..... don't pay the fines if you get them, they will soon realize it isn't you. I have apt/condo living!!!!
