Pet Friendly Herbs

Picture of a dog and cat

Herbs have been with us for hundreds – in some cases thousands of years. They have played a role in folk medicine, religion, and cooking. Today many people around the world like to grow their own herbs or buy them to use in recipes. Pets can also benefit from some of the same herbs that are good for humans. Here’s a quick look at some of the pet friendly herbs people use today. You can find out more about each herb by following the links.

Cautions about Herbs for Pets

We have provided a list of herbs that are safe for dogs and cats with some brief information about each one. Both dogs and cats can have these herbs in small amounts with a few exceptions. Oregano is one exception. While oregano is safe for dogs in small amounts, it can be toxic for cats. Allspice and cloves can be toxic to both cats and dogs.

Herbs discussed here refer to using them the same way they are used as an ingredient in human foods. That typically means use of the chopped, fresh leaves or the dried, ground version sold in containers in grocery stories. Some herbs can also be used as a tea. However, there are warnings against giving dogs and cats essential oils made from virtually all herbs because these oils are very concentrated. Many essential oils can be toxic to your pet.

As always, we recommend that you talk to your veterinarian before changing your pet’s diet. Some herbs can have noticeable effects on a dog or cat’s health. Many herbs can affect blood sugar levels and digestion. Some herbs can affect other health issues. Just because they are herbs and seem “natural” doesn’t mean that they can’t pack a punch. You should treat them with caution when giving them to your cat or dog.

The seeds are considered to be a spice. All parts of the plant are edible and safe. Cilantro is closely related to parsley and sometimes called “Chinese parsley.” Cilantro/coriander has been used to help with minor digestive issues such as gas. For some dogs it seems to act as a stimulant to the appetite. It appears to help reduce anxiety in some dogs and even helps pets sleep better.

Picture of peppermintPeppermint is a hybrid mint plant that now grows naturally throughout Europe and the Middle East. Put thoughts of peppermint candy out of your head! This is a plant, not a candy.

Peppermint also contains menthol which is why it’s so popular in dental products. It has antibacterial properties that kill germs that cause dental plaque.

Picture of vanilla beanWe usually take vanilla for granted but it is one of the most expensive spices in the world. Vanilla comes from tropical climbing orchids that are very labor-intensive to grow and require hand-pollination. Natural vanilla extract contains hundreds of compounds, including vanillin. It has the potential for many health benefits. The vanillin in vanilla is associated with antioxidant and anti-inflammatory properties, neuroprotection for the brain, and is being studied in anti-cancer research. Vanilla itself is not harmful to cats and dogs. However, vanilla is normally used in many foods and beverages and some of them could be harmful to pets. Avoid giving your pet foods with vanilla that could contain other harmful ingredients such as xylitol, alcohol, or large amounts of sugar.

Very, very small amounts of cloves could be safe for dogs but it’s usually not worth the risk. Even a small amount of cloves can be toxic to cats. Warning signs that your pet might be having problems after eating cloves include vomiting, diarrhea, and lethargy… more

Oregano (Cats ONLY)

Oregano contains a number of antioxidants. As part of herbal medicine, it has been used for a vast array of ailments for centuries. Recent research suggests that it may be effective as an antibacterial, anti-inflammatory, for regulating blood sugar and lipids, and even for fighting cancer. Oregano is safe for most dogs in small amounts. However, it is toxic to cats even in very small amounts.

How to Use Herbs

If you are using an herb for your pet, you can generally use it the same way that you would use it in your own food. In most cases, herbs for cats and dogs are only used in very small amounts.

Fresh herbs are normally stronger than dried herbs. They are usually made up of leaves from the plant. You can chop the fresh leaves and add them to your dog’s food.

If you are using dried herbs from a container, very small amounts are used. (See the suggestions provided for each herb.)

Some herbs can be made into teas such as basil, parsley, and peppermint. You can generally pour boiling water over the fresh leaves, allow it to steep for a few minutes, let it cool, and share it with your pet. Not all pets will like these teas. You can put a little in your pet’s food. Dogs can be more willing to try herbal tea added to their kibble than cats but you can try.

Pets and Herbs

Most of us tend to believe that herbs are beneficial. Many of them are helpful. However, it’s important to remember that for ages before modern medicine, people used herbs medicinally. Today many herbs are being researched for their value in fighting diseases. Used indiscriminately, some herbs can be dangerous, especially if your pet has any pre-existing conditions. Please use care when giving your cat or dog any herbs. If your pet has any health issues, talk to your veterinarian before adding any herbs to his or her diet. You can also talk to an herbalist or someone who is licensed in complementary or alternative medicine  to assist you in choosing herbs for your pet’s diet.
