CBD for dogs and cats in Switzerland: what owners need to know

CBD for pets is permitted in Switzerland, but it is neither a miracle cure nor harmless at any dose. This page summarises what the evidence actually supports, how to dose by body weight, why cats must be treated differently from dogs, and why THC is dangerous for dogs.

At a glance

  • CBD products below 1% THC are freely available in Switzerland, including for animals; they may not be advertised as medicines.
  • Starting rule of thumb: 0.1–0.2 mg CBD per kilogram of body weight, twice daily, increased slowly over 7–10 days.
  • The strongest evidence covers osteoarthritis-related pain in dogs; for anxiety and epilepsy the data is weaker.
  • Cats metabolise differently and are more sensitive to terpenes — use low-strength, low-terpene oils only.
  • THC is toxic to dogs. If you suspect ingestion, go to a vet immediately.

What the evidence actually shows

The most robust evidence comes from controlled studies at Cornell University and other veterinary groups in dogs with osteoarthritis: over several weeks, treated animals showed measurably better mobility and fewer pain signs than controls, with good tolerability. For anxiety, separation anxiety and epilepsy there are smaller studies with inconsistent results.

For cats the data is considerably thinner. It is known that cats absorb and metabolise CBD differently from dogs and that higher doses more often cause drooling, vomiting and lethargy. Starting cautiously matters even more here.

The honest bottom line: CBD does not replace a diagnosis. Limping, behavioural changes or seizures should be investigated before any oil is used.

  • Good evidence — Osteoarthritis-related pain and mobility in dogs.
  • Mixed evidence — Anxiety, fireworks stress, separation anxiety.
  • Weak evidence — Epilepsy, skin conditions, supportive cancer care.

Dosing by body weight

The standard rule is: start low, go slow, document the effect. A typical starting point is 0.1 to 0.2 milligrams of CBD per kilogram of body weight, twice daily. After seven to ten days the dose can be raised in small steps if no adverse effects appear and the desired effect is still missing.

Side effects and interactions

The most common adverse effects are drowsiness, soft stools, increased drooling and a slightly altered appetite. In dogs, prolonged use has been associated with a rise in alkaline phosphatase — a reason to check liver values periodically during long-term use.

Interactions matter more: CBD inhibits cytochrome P450 enzymes and can slow the breakdown of other drugs. In animals receiving antiepileptics, painkillers or cardiac medication, CBD belongs in veterinary hands.

  • Common — Drowsiness, soft stools, drooling — usually dose-dependent and reversible.
  • Monitor — Have liver values checked periodically during long-term use.
  • Caution — With antiepileptics, NSAIDs and cardiac drugs only after veterinary advice.

THC poisoning in dogs: recognising and acting

Dogs have a high density of CB1 receptors in the cerebellum and react to THC far more strongly than humans. Typical signs of intoxication are staggering, tremors, dilated pupils, urinary incontinence, sound hypersensitivity and, in severe cases, reduced consciousness. The most common cause is not CBD oil but eating edibles, joint remnants or discarded material on a walk.

If you suspect it: go to a vet immediately, say honestly what the animal may have eaten, and bring the packaging if possible. With prompt treatment the prognosis is good — withholding information costs time and worsens it.

What to look for when buying

The market is opaque and quality differences are large. Four criteria separate usable products from the rest.

  • Batch lab report — CBD content, THC content, pesticides and heavy metals must be documented.
  • THC below 1% — For animals, lower is better. Broad spectrum or isolate is preferable for cats.
  • Carrier oil — MCT or olive oil. No essential oils, no xylitol, no flavourings.
  • Clear mg labelling — Milligrams of CBD per drop — without it, reliable dosing is impossible.

Frequently asked

Is CBD for dogs legal in Switzerland?
Yes. CBD products containing less than 1% THC are freely available, but they may not be advertised as veterinary medicines.
How much CBD does my dog need?
Start at 0.1–0.2 mg per kilogram of body weight, twice daily, then adjust slowly over 7–10 days.
Can I give my normal CBD oil to my dog?
Only if it is free of essential oils, flavourings and xylitol and the mg-per-drop content is known. Lower concentrations are easier to dose.
Does CBD help with fireworks anxiety?
Some animals respond well, but the evidence is inconsistent. Start several days in advance rather than on the evening itself.
How long does CBD take to work?
30–60 minutes orally for acute effects; in osteoarthritis, improvement usually appears after two to four weeks of regular use.
What if my dog ate THC?
Go to a vet immediately. Typical signs are staggering, tremors, dilated pupils and incontinence. With rapid treatment the prognosis is good.
