What Does Citronella Really Do to Dogs?

Citronella spray collarMy Paws for Thoughts are just what they say – thoughts. I don’t profess to be an expert on this or feel that we should believe everything we read, but this does make one think.

My train of thought started with an email I received this morning from a man with a Cocker Spaniel and he was the four-year-old dog’s third home. He had cancelled the appointment because my simple telephone advice worked instantly.

The man had told me about poor Bertie’s ‘strange compulsion of growling and digging the carpet’ and his barking was so bad that he had been using a citronella collar. After talking to me he abandoned the collar. Immediately the digging stopped. ‘Bertie no longer grumbles and growls to himself or digs the carpet any more, and though he barks this is purely as a warning that someone is approaching the house and his barking is what you would expect from any dog. He is now not stressed with the result that we are both much happier’.

Citronella can be found in sprays and bark collars. The collar is placed on the dog’s neck. Each time it barks, a canister squirts citronella spray in front of the dog’s nose.

It got me thinking about what citronella spray up a dog’s sensitive nose must do to him – and how long the after-effect must last for, killing his sense of smell. It seems to me that as smell is dog’s major sense, it must be like ourselves being blinded with a bright light. It’s not over and done with immediately it is dispensed, so the punishment continues even after the barking has stopped.

Behaviourally the dog isn’t learning to stop barking – the emotion that makes him want to bark is being suppressed. It is bound to erupt elsewhere – as so graphically exhibited by Bertie’s frantic digging and grumbling.

I got to thinking about the physical effects of citronella spray.

I found this on Drugs.com: “Animal toxicity studies have shown that citronella oil has an LD 50 in mice of 4600 mg/kg and in rats of 7200 mg/kg. A dose of 1 to 4 mL/kg given by stomach tube in rabbits caused paralysis, coma, and death. At least 1 case of death has been reported in a child who ingested an unknown quantity of citronella oil. A review of 5 cases of childhood citronella oil poisoning suggests that dilution of the oil following ingestion may be sufficient to treat most cases of ingestion and that emesis may be induced with a relatively low risk of major pulmonary complications. If spontaneous vomiting has occurred, observation for respiratory symptoms is required.”

Now this IS scary: Citronella Collars – May contain: Pesticides, Booze and Refrigeration Coolant.

To quote Yvette Van Veen: ‘Natural does not mean safe or free from side effects.  Natural can kill you.’ Here are some of the points she raises:

  • Citronella is an insect repellent – a pesticide.
  • Natural citronella oil may contain methyleugenol, which has been shown to be carcinogenic in animal studies.
  • Citronella can cause lung cancer if ingested.
  • It’s important to know that most products on store shelves contain multiple ingredients.  A canister of citronella spray is not necessarily 100% citronella.The safety page for the canister of 1% citronella spray also contains approximately 10% ethanol and up to 90% Tetrafluoroethane.
  • Warnings include: Eye: may cause irritation. Skin: may cause irritation. Inhalation:  may cause dizziness and loss of concentration
  • Ethanol is alcohol.  It makes you drunk.
  • Tetrafluoroethane is a refrigeration coolant – it makes car air conditioning units cold and it is also used in various spray canisters.  This chemical is also a street drug, giving abusers an easily obtained rush.

If we want our dog to control his barking and for him to remain healthy both physically and mentally, then we should put in a bit of time and trouble to see why he is barking – what emotion is driving him to bark, and to work on that.

Barking, after all, is their main way of audible communication. It’s simply cruel to stifle it altogether.

Here is the story of a dog I helped whose troubles could well have started by the use of some sort of anti-bark collar.

    It’s the act of spraying, that triggers the dogs to stop barking, not necessarily the citronella itself. Replace the liquid inside with WATER.
    Citronella to control fleas and ticks. Not necessarily the barking
    Citronella TRUE HYDROSOL by Muddy Paws from the Philippines, it’s a single-ingredient product makes it safer for both human and dog.

    We have been using this type of collar off and on for a few years. Its only now that our girl has shown redness on her muzzle. We can’t attribute it to anything else as her food is the same and no allergies to it (Honest Kitchen) she doesent get into the trash and we dont use anything on her hair or skin… It must be the spray from the collar!! We have not put it on her for about 2 weeks and still see a bit of the redness/irritation.
    Why dont they make these collars that just spray water vapor?!

      They do – but there are much better ways to teach a dog not to do something. Punishment will nearly always backfire in some way and it really isn’t necessary – but that’s off topic:-)

    My neighbour complains about our 2 miniature schnauzers who are 6 months old and very active. The one schnauzer has just recovered from a spider bite causing anaphylactic shock and a 3 day hospital stint. His liver was compromised because of the bite but is recovering nicely. I refuse to use citronella spray on the advice of my neighbour for this reason. Besides, the dogs were barking in our house in the early afternoon and apparently annoyed my next door neighbour.

      I’m pleased you are ignoring this advice. I would advise getting some behaviour help so that the dogs no longer feel they need to bark so much. Cover look-out windows with static window frosting perhaps?
