For Puppies & Young Dogs:
 Feed 80% meat and mix with 20%  puree

For Adult Dogs:
Feed 70-80% meat and mix with 20-30% puree

For Senior Dogs:
Feed 60-70% meat and mix with 30-40% puree

For kibble/wet food users: 
Just top their regular meal with about 10% puree as a healthy boost.

Always store in a cool, dark place. Shake well before use - it's natural for some separation. The puree mixes best when at room temperature.
