What you want to do is get one that is more roughly shaped but still recognisable as a paw print and have the paw part be made of a soft material that hard enough to leave paw prints in dort but inconsistentently so the paw prints in the dirt aren't perfectly uniform
It would also be better to have the paw part be casted from a real dog paw
I think they meant, that they also pooped, since the neighbor was ranting about the poop ( it must have been a dog in their logic, because of the dog footprints )
