This 300mg pet CBD oil is perfect for large dogs like German Shepherds, Great Danes, etc. At King Kanine, we use organic, broad-spectrum CBD oil and combine it with oils like krill oil and hemp oil. Krill oil is rich in omega-3, antioxidants, and has powerful anti-inflammatory properties. Some use pet CBD to promote healthy immune systems in dogs and offer relief from a wide range of symptoms, including pain, noise phobia, stress, etc. We only use hemp-derived CBD that’s grown exclusively in the United States, and we test all of our products for purity, safety, and consistency. This pet CBD oil comes with a 30-day money-back guarantee and free shipping.
