I have been using Canna-Pet advanced on my Portuguese Podengo Pequeno, Townie, since mid-December and it has really helped him overcome his fears and anxiety, therefore greatly increasing his speed and confidence in the agility ring and in other sports he does. I saw a noticeable difference in him within the first week and a very big difference within 5 to 6 weeks. Thank you Canna-Pet for giving him his confidence back.
