The effects of CBD are similar in humans, dogs, cats, and other pets because just like humans they too have an endocannabinoid system whose functioning is similar to that of humans. Pets can also suffer from anxiety or other phobias and CBD takes care of this. There is a strong body of evidence that shows that CBD is a successful antiemetic, controlling both nausea and vomiting while also stimulating appetite. Talking of tumors or cancer, the most common treatment for this among pets is chemotherapy but it comes with some side effects too. However, according to different researches, CBD oil for pets helps reduce cancer without ill effects.
