I know that dogs have a sense of smell far greater than humans, and Tikva is [half] a scent hound, but how does she know if something delivered has food in it for her? I do not mean her raw meat as of course she knows Mikhaël who brings it, but packages/cartons delivered by courier or the mailman. Whether freeze-dried or air-dried, packed in a sealed, thick re-recyclable plastic bag, packed inside a re-recyclable cardboard shipping/postal carton, how does she know which one is for her?
When you consider how scent dogs can detect the tiniest amount of drugs that are concealed exceptionally well, it's no surprise Tiki can find the proverbial needle in a haystack where food is concerned Rosie knows the difference between things she won't get a bite of and things she will be given. For example, if I have a chocolate biscuit, she'll not even look up. If I have a ginger biscuit or digestive, she's at my feet giving me the big brown eyes
