William Walker hemp seed oil "Hemp Hero" can be mixed with the normal food once a week. At the beginning, the addition of the oil should still be a little lower, in order to accustom the organism of the dog slowly.
The rule of thumb for the dosage is:
1x per week
2,5 ml - 5 ml for smaller dogs
5 ml - 10 ml for medium dogs
10 ml - 15 ml for large dogs
This information is indicative. The actual requirement depends individually on breed, age and daily activity.
Stored in a cool, dark & dry place, the durability is about 9 months.
