I have 2 chocolate
labs they are
brothers 8 years old and are both dedicated poop eaters ive tried all the above things to no avail we just pick it up every time but still miss the odd one now and then, they both know its bad and sometimes they know one has been missed but they give them selves away, they stand still hoping I haven't spotted it and if i'm far enough away they get it and
run off, I also have a great dane and he thinks they are disgusting....
