My 12-year-old dog, Cocoa, is a bone cancer survivor and has benefited from Canna-Pet  Advanced Formula CBD Oil for about a year and a half.  Her integrative cancer treating veterinarian, who is also a research vet, recommended Canna Pet CBD as a high-quality product.  Cocoa has a sensitive stomach and cannot tolerate regular anti-inflammatory drugs.  The CBD oil has proven to relieve discomfort from her arthritis.  She has a noticeable increase in activity when she is taking the CBD oil. Great product
