Frequently Asked Questions
Can I give calming chews every day?
Yes, but choose a product designed for daily use like Zylkene or Purina Calming Care. Melatonin-based chews should be situational only.
What if my dog spits out the chew?
Try hiding it in a small amount of peanut butter or wet food. Most chews are soft and meat-flavored, but picky dogs exist!
Are calming chews safe for puppies?
Most are safe for dogs 12 weeks and older. Always check the label — avoid melatonin for puppies under 6 months.
