How long should I administer this supplement to my dog before I see results?

It really depends on why you are giving Cannanine to your dog. If anxiety, it should be almost immediately (if the dosing is correct). If you are giving to help with joint pain, it may take a longer period of time for the body to respond.
Please reach out to our product specialists who can give you a more exact answer. Also – they can answer dosing and frequency questions as well.
