Is mint safe for dogs?

Can dogs have it in their mouth without it going into their system? If so what is the difference between the 2?


Yes dogs can have it.

Here is a study that showed that dogs and cats could extract the active ingredient from chewing on mint (I guess this was just a placebo effect). The study was using very large doses of menthol in the mint (like a couple grams of ground mint per day).

That study also showed that dogs have a higher metabolizing rate of mint and that the menthol in mint is absorbed at a slower rate (again this was probably just a placebo effect)

There is also a study that showed that dogs could extract the active ingredient from chewing on mint, but that dogs had a slower metabolizing rate (which again was probably just a placebo effect).

Also here is a study on what the effects are when a dog eats menthol:

Menthol is derived from the essential oil of MENTHOLUS PINEUS

(syn:Mentha arvensis L. syn:Mentha piperita L., syn:Mentha spicata

L. syn:Mentha suaveolens Ehrh., syn:Mentha aquatica L., syn:Mentha

pulegium L.). It is a monocyclic compound. The menthol content in

essential oils of many varieties of MENTHUS (about 70-80%) and even

the leaves is around 7% but in the whole plants and in the oil it is

around 30% (G.H. Blythe, J.R. Macrae and P.G. Schuller, 1983). The

menthol content in peppermint (Mentha piperita) is about 10%

(M.A. Gentry, A.M. Lathrop, D.D. Echlemann, 1985).

The menthol content of peppermint and spearmint is not easily

determined, because it is difficult to standardize peppermint oil,

because the menthol is volatile.

The physiological actions of peppermint (Mentha piperita L.) and

spearmint (Mentha spicata L.) include carminative and spasmolytic

actions (M. Pahlavi and R.M. Mokarrameh, 1967).

Although peppermint oil has a slightly warming effect, the common

wisdom that it causes the body to sweat because of its

spasmolytic action has not been substantiated (S.L. Schurman,


Peppermint oil may be combined with peppermint oil for the

production of toothpastes and mouthwashes (M.F. Schafer, 1995).

Peppermint (Mentha piperita) and spearmint (Mentha spicata) are

good in gastrointestinal disorders as well as in some respiratory

problems (A.J. McLeod and G.A. Coady, 1985). Peppermint oil is a

common additive to cough mixtures (M.E.E. R.B. King, 1982).

Peppermint oil is a component of many skin products, such as hair

tonics, soaps, and shampoos (S.H. Jang, 1992). Mentha

piperita L., has been suggested to have antimicrobial activity

against dental and skin problems. Peppermint oil has been

suggested as an aid for weight control and has also been found

useful in relieving anxiety and inhibiting gastric and duodenal

acid secretion (M.P. L. R. Marnell, and D.M. Williams, 1992).

Peppermint oil has been traditionally used in the treatment of

bronchial problems (A.J. McLeod and G.A. Coady, 1985). However,

there is no evidence that it works. Menthol and menthone, the

active agents in the oil, are active against bacteria and yeast

and have been used as antiseptics (S. H. Kang, 1996). The peppermint

oil has been used for the treatment of respiratory diseases, and

it has been used to relieve upper respiratory symptoms and sinus

congestion (S.P. Kim, 1995).

However, this paper is an in vitro study, not an in vivo study, so I'd suggest that it's too early to conclude that it will work.


The answer by @John Bollinger is a good one.

In addition, menthone and menthol are quite similar in chemical structure (i.e. they both share a methyl group attached to an oxygen and attached to a cyclopentane ring).

If you go to the Wikipedia entry on menthol (, you'll find

it is believed that menthol's antiseptic qualities come from the inhibition of the microbial growth of the microorganism responsible for colds (S. H. Kang, 1998, R.K. Kaul, G.C. Singh, and S. H. Kang, 1998).

If you can find a reference to the same study by S. H. Kang as in @John's answer, I'd bet it would say something like

... it has been proposed that menthol possesses antimicrobial activity...

or has been proposed that menthol inhibits bacterial growth...

or even has been proposed that menthol inhibits microbial growth.

This is more likely to be a chemical reason for its action rather than a psychological reason.


You can also use eucalyptus oil

There are no studies on the biological properties of eucalyptus oil, but studies have suggested that it has anti-septic, anti-fungal, anti-viral, and anti-bacterial properties.

Another common one is camphor. However, it is commonly used as a cleaning agent.


One more thing, a natural solution to the problem (even if you don't believe it) is simply open your window.
