Start with suitability
Age, body condition, health and activity matter; ask a veterinarian when there is any concern.
Fit before load
The pack should sit securely without interfering with normal movement.
Keep loads conservative
This site does not prescribe loading percentages; follow veterinary and manufacturer guidance.
Balance both sides
Unevenly packed pockets can shift how the harness sits.
