When we first got one of our dogs off the street, she was incredibly food motivated. She would hop the fence and roam and bring back cabbages, avocados, cauliflower, chips, and anything else she could find to snack on. Those are just examples we witnessed. But she always came back before we got home from work.

Now, 7 years later, she's picky. She'll spit out some food I give her if it isn't appealing enough. She can still obviously be motivated with food and treats, but it's far less unconditional.
