Hemp vs CBD: The Real Difference

“Hemp” on a label can mean three very different things. Hemp seed oil is a food oil with essentially no CBD. CBD oil / hemp extract contains CBD and other beneficial compounds – this is what people mean by CBD. Marijuana is the high-THC cousin you should keep away from pets. For dogs and cats, the sweet spot is a broad-spectrum hemp extract: all the beneficial cannabinoids, with the THC removed.

The three things people call “hemp”

This is where almost everyone gets confused, so let us make it simple.

1. Hemp seed oil – pressed from hemp seeds, sold as a food or skin oil. It has omega fatty acids but essentially no CBD. Fine as a nutritional oil; useless if you actually want CBD. If the label says “hemp seed oil,” you are not buying CBD.
2. CBD oil / hemp extract – made from the leaves and flowers of the hemp plant, and contains CBD plus other cannabinoids. This is what people mean when they talk about CBD for dogs. The terms “CBD oil” and “hemp extract” get used interchangeably, so look past the name to what is actually in it.
3. Marijuana – a cannabis plant bred to be high in THC, the intoxicating compound. THC can be toxic to dogs and cats. Keep it away from pets.

So “hemp oil” is ambiguous on purpose – some products lean on the word “hemp” to sound like CBD when they are really just seed oil. Read the cannabinoid content, not the marketing.

Why focus on the type of extract, not the buzzword

Once you know it actually contains CBD, the thing that matters is the type of extract. Our view, at Dr. Fossum’s, is that the more of the natural plant compounds you keep, the better they work together – cannabinoids, terpenes, and flavonoids acting in concert. This teamwork is called the entourage effect.

• Full spectrum – includes THC along with everything else. Often chosen by people; we do not recommend it for pets because THC can be toxic to them.
• Broad spectrum – the same beneficial cannabinoids, terpenes, and flavonoids, but with the THC removed. Think of it as full spectrum minus the THC. This is what we recommend for dogs and cats – you get the entourage effect without the THC risk.
• CBD isolate – pure CBD and nothing else. It is the cheapest form and you lose the entourage effect, so we do not recommend it. Very cheap CBD oils are often isolate-based.

Because our products have the THC removed, an accidental overindulgence is far less dangerous than it would be with a THC product – which is the whole point of choosing broad spectrum for a pet.

CBG and CBN – the other cannabinoids worth having

CBD gets the headlines, but it is not the only useful cannabinoid. CBG and CBN are two others that contribute to the entourage effect and bring their own benefits. A good broad-spectrum extract keeps these in the mix rather than stripping everything down to a single compound – another reason to skip isolate.

Which should you give your dog or cat?

For nearly every pet, the answer is a broad-spectrum hemp extract with a clear CBD strength and a certificate of analysis. It gives you the whole-plant benefit without the THC. Match the product to the species – cats are more sensitive and should have a cat-formulated product. See CBD for Dogs and CBD for Cats for the species specifics.

How to verify what you are actually buying

Do not trust the front label. Check the certificate of analysis (COA) – the independent lab report – and confirm it actually contains CBD (and ideally CBG/CBN, terpenes), that THC is at or below the legal limit, and that the milligram strength matches the label so you can dose accurately. No COA, no purchase.
