Avoid essential oils with puppies

Essential Oil Safety For Dogs

You should always be cautious using essential oils with puppies. In general, it’s best to avoid their use on puppies altogether. Puppies, like babies, aren’t necessarily able to metabolize things the way adult dogs (and people) can.

  1. Consult with your veterinarian before doing anything.
  2. Only use therapeutic grade, high quality oils from reputable companies that specialize in essential oils.
  3. Reference the list of essential oils that are toxic to dogs.
  4. Avoid the dogs eyes, nose, genitals and anal area.
  5. Never use with puppies under 10 weeks old, pregnant dogs, dogs on certain medicines or elderly dogs.
  6. Dilute, dilute, dilute. Seriously, dogs don’t need the same amounts of essential oils that we do. Check the recommended dilution ratio specifically for dogs which is typically a 1:50 ratio.
  7. Carefully watch your dogs reaction.
