Care, Cost and Maintenance
Start with the Lowest Dose
Begin with the recommended dose for your dog's weight, then adjust gradually as needed. Observe for any adverse reactions.
Use Consistently
For best results, give the treat 30-60 minutes before the anticipated stressful event. Consistent use can enhance effectiveness.
Store Properly
Keep treats in a cool, dry place away from direct sunlight. Check expiration dates and discard if any off smells or mold appear.
