Hi and congrats on your new family member
Our Heidi is 9months and she is a "poop-dog" as well (still
)
She never touched shoes or things in the house as a pup, except for cat toys, but she
always ate poo or rocks outside (especially going for the kitty litter).
We were so frustrated at 1st and still are a bit now.
With Heidi on a leash, we'll let her smell poop and tell her NO and LEAVE IT. It's slowly working, but not perfectly (as she still goes for other dog's mess sometimes on a walk or in the park when off leash). The message is getting though slowly however, as she recently just smelled, looked up at us and came running instead
.......so hopefully with patience and consistency she will become less obsessed.
Goodluck with your pup and I am still crossing my fingers its a maturity thing.
