Pet Releaf CBD hemp oil 1000 is a more concentrated form of CBD oil and intended for those dogs that need a higher potency product. Our CBD hemp oil 1000 is grown at the largest USDA certified organic hemp farm in the United States. We planted a specialized proprietary strain, PR-33, grown specifically with pets in mind. Since we use the entire plant (seeds and stalk), our CBD hemp oil 1000 provides all of the benefits of CBD while also providing the multitude of additional benefits provided by the terpenes and flavonoids.
