We know CBD is safe for dogs because all vertebrate animals, just like us humans, have an endocannabinoid system (ECS). The ECS is a complex cell-signaling system first identified in the early 1990s and it is what processes CBD in the body. While researchers are still studying the ECS, they have found links to how it regulates important life functions, including memory, sleep, appetite, and mood.
CBD and ECS receptors are found throughout the body of you and your pets, and they interact to establish a bridge between the body and mind. There are two endocannabinoid receptors, CB1 and CB2. The CB1 receptors are found mostly in the nervous system. CB2 receptors are found mostly in the peripheral nervous system, particularly in immune cells. When products such as CBD oil are ingested, they interact with the CB1 and CB2 receptors, stimulating the desired effects.
