This is Sandy. She is a 14-year-old Golden Retriever. She had been “acting out” in the evenings, by a continuous barking. My veterinarian said that older dogs do behave this way as they age, due to various conditions. One of those is simply anxiety. We started her on the Canna-Pet Advanced capsules for large dogs, and her barking in the evenings has subsided significantly. She still has a mind of a young dog, and is a joy to be with. Thank you, Canna-Pet!
