NEVER APPLY IT to areas that the animal can lick.”

Make sure you always use a carrier oil your dog is compatible with, such as jojoba, olive, or coconut to name a few. You can even use water as well.

Choosing Essential Oils

Many problems regarding an essential oil can be attributed to its quality. Choosing the right essential oil is important because not all of them are created the same. When it comes to personal use or for your dogs, you need to seek the highest quality therapeutic grade essential oils.

The purity of an essential oil is a common issue, and this is because its achievement is expensive. For example, it takes nearly one hundred pounds of lavender plants to produce one pound of Lavandula angustifolia essential oil. Because of this, many producers will dilute a pure essential oil with other carrier oils or even add artificial fragrances to create a greater production. Natural News gives us the following guidelines to make sure you buy the purest therapeutic essential oil:

  • EO’s should not be oily or leave a greasy residue.
  • Packaging should include the common name (Tea Tree Oil), the Latin binomial (Melaleucaalternifolia), the country of origin, the method of distillation, the part of the plant used, lot number, amount of oil in bottle, contact information of the company, how the plant was grown, and the words “100% pure essential oil” or the ingredients, if in a carrier or blend.
  • Price usually dictates quality.
  • Not all bottles of the same size yet of different oils should be priced the same. In other words, if they carry 50 different types of oils, yet every 5ml bottle is $7.40, there is something wrong, and you can guarantee these oils have been adulterated in some way.
