so she isn't able to sniff around where I can't see.
Honestly, "doodle's" nose is becoming legendary. I'll think she's smelling the bush (or urine on it) and she'll come out with a bagel in her mouth! (yes, this actually happened!) I have learned that she can find all manner of things that are clearly obvious to her nose and undetectable to my eyes. If your pup is intent on what she's smelling, there's a reason for it.
