As pet owners, we love to pamper our furry friends and make them look their best. One recent trend that has gained popularity is painting a dog’s nails with human nail varnish. While it may seem harmless, there are some essential things to consider before painting your dog’s nails with human nail varnish.

Toxic Ingredients in Human Nail Varnish

Human nail varnish contains various chemicals that can be toxic to dogs if ingested or absorbed through their skin. Some of the most common harmful ingredients found in nail varnish include formaldehyde, toluene, and dibutyl phthalate (DBP). These chemicals can cause various health problems in dogs, including skin irritation, respiratory issues, and even organ damage, so it’s best to avoid putting human nail varnish on your dog.

Formaldehyde is a colourless gas with a pungent odour commonly used in nail varnish as a preservative. It is a known carcinogen and can cause respiratory issues, skin irritation, and allergic reactions in dogs.

Toluene is a clear, colourless liquid used in nail varnish to help it adhere to the nail. It is a toxic chemical that can cause neurological damage, respiratory issues, and skin irritation in dogs.

Dibutyl phthalate (DBP) is a colourless, oily liquid used in nail varnish to make it more flexible. It is a known endocrine disruptor and can cause reproductive issues, developmental problems, and liver damage in dogs.

Exposure to these chemicals can harm dogs, especially if they are ingested or absorbed through the skin. It is essential to read the labels of any nail varnish products before using them on your dog and avoid products containing these toxic ingredients.

What Could Go Wrong?

If a dog ingests or absorbs toxic chemicals from human nail varnish, it may experience a range of symptoms, including vomiting, diarrhoea, lethargy, and difficulty breathing. In severe cases, exposure to toxic chemicals can even be fatal. Additionally, if a dog’s nails are painted with human nail varnish, they may be more likely to chew or lick their paws, leading to further ingesting toxic chemicals.

How to Remove Human Nail Varnish from a Dog’s Nails

If you have painted your dog’s nails with human nail varnish and are concerned about their safety, removing it as soon as possible is important. To do this, you can use a non-toxic nail varnish remover specifically designed for dogs. Alternatively, try soaking your dog’s paws in warm, soapy water and gently scrubbing the varnish with a soft-bristled brush.

Is Nail Varnish for Humans Safe for Dogs?

In general, using human nail varnish on dogs is unsafe. The chemicals in human nail varnish can be toxic to dogs and cause various health problems. Additionally, human nail varnish is not designed to adhere to a dog’s nails and may chip or peel off, which can be a choking hazard if ingested.

Are There Any Dog-Safe Nail Varnishes?

Fortunately, a variety of dog-safe nail varnishes are available on the market. These varnishes are designed for dogs and are made with non-toxic, pet-friendly ingredients. Some popular brands of dog-safe nail varnish, which I use, include Warren London Pawdicure Polish Pens and Color Paw Nail Polish.

Warren London’s Pawdicure Polish Pens are a game-changer for pet grooming. These pens are water-based and non-toxic, ensuring your pet’s safety. The polish dries in under 40 seconds, but you may need to apply a few coats to achieve the desired look. The best part is that removing the polish is a breeze. Soak your dog’s paws in water or use a soaked cloth or cotton ball.

Advantages of Using Dog-Friendly Nail Pens Over Human Nail Varnish

For several reasons, dog-friendly nail pens are a popular alternative to traditional human nail varnish. One of the main advantages of using a nail pen is that it is much easier to apply to a dog’s nails than a brush. With a nail pen, you can draw the polish onto your dog’s nails, making it easier to control the application and avoid getting the polish on your dog’s fur or skin.

Another advantage of using a nail pen is that it can be less messy than traditional nail varnish. Because the polish is contained in a pen, there is no risk of spills or drips, which can be especially important if you paint your dog’s nails for the first time.

In addition, many dog-friendly nail pens are designed to dry quickly, which can be helpful if your dog is not used to having their nails painted. Quick-drying polish can help reduce the risk of smudging or smearing, which can be frustrating for you and your dog.

Overall, dog-friendly nail pens can be a convenient and easy way to add colour to your dog’s nails without the risks associated with using human nail varnish. Just be sure to choose a high-quality, non-toxic product specifically designed for dogs to ensure your pet’s safety and comfort.

The Importance of Considering a Dog’s Sense of Smell When Using Human Nail Varnish

Dogs have a compelling sense of smell, with an estimated 300 million olfactory receptors in their noses compared to the 6 million found in humans. This means that dogs can detect scents that are far too subtle for humans to notice and can even distinguish between individual components of complex odours.

The strong chemical odour can be overwhelming for dogs regarding human nail varnish. This is because dogs have a much more sensitive sense of smell than humans and can detect even the slightest traces of chemicals in the air. The chemicals found in human nail varnishes, such as formaldehyde and toluene, can be particularly intense and unpleasant for dogs.

Is there a difference in odour between dog-friendly and human nail varnishes?

Dog-friendly nail varnishes are typically made with non-toxic, pet-friendly ingredients safe for dogs to ingest or absorb through their skin. As a result, they may not have the same strong chemical odour as human nail varnish. However, it is essential to note that some dog-safe nail varnishes may still have a slight odour, as they are still designed to adhere to a dog’s nails and may contain some of the same ingredients as human nail varnish. If you are concerned about the odour of dog-safe nail varnish, look for brands that advertise themselves as low-odour or fragrance-free.

5 Ways to Pamper Your Dog Without Using Human Nail Varnish

There are many ways to pamper your dog that do not involve using human nail varnish. Here are some ideas:

  1. Give your dog a massage: Just like humans, dogs can benefit from a relaxing massage. Use gentle, circular motions to massage your dog’s muscles and help them relax.
  2. Take your dog on a special outing: Whether it’s a trip to the dog park, a hike in the woods, or a visit to a pet-friendly restaurant, taking your dog on a special outing can be a fun way to pamper them.
  3. Buy your dog a new toy: Dogs love to play, and a new toy can provide hours of entertainment and stimulation.
  4. Make your dog homemade treats: There are many recipes available online for homemade dog treats that are healthy and delicious.
  5. Give your dog a spa day: Treat your dog to a bath, a brush, and a nail trim.

Remember, the best way to pamper your dog is to spend quality time with them, show them love and affection, and provide them with the care and attention they need to be happy and healthy.


In conclusion, while it may be tempting to paint your dog’s nails with human nail varnish, it is vital to consider the potential health risks. Instead, opt for dog-safe nail varnish to keep your furry friend looking stylish and safe.
