I\'ve had some really awesome help on my previous questions for detecting paws and toes within a paw, but all these solutions only work for one measurement at a time.

After skimming your linked code, it seems to me that you are better off not designing a Dog class at this point. Rather, you should use Pandas and dataframes. A dataframe is a table with columns. You dataframe would have columns such as: dog_id, contact_part, contact_time, contact_location, etc.
Pandas uses Numpy arrays behind the scenes, and it has many convenience methods for you:
my_measurements['dog_id']=='Charly'my_measurements.save('filename.pickle')
