We began our journey in 2009. Our parent company first launched with the goal to never use artificial flavorings or ingredients. We found that this was not common place, so we had to become the experts.

Armed with Ph.D. Chemists, Nutritionists, and more (at times, even World Class Master Chefs), we built an ISO Certified manufacturing facility and focused on 100% USA made ingredients from "critical fluid extraction".

What is "critical fluid extraction"? That's where we extract from the actual base source to develop an essential oil.

For example, imagine the natural flavor of vanilla as it is extracted from the actual vanilla bean itself.

We have acted as visionaries and advocates for consumers across multiple industries, responsibly.

We are committed to the highest standards, attention to detail, and above all, to remain 100% Made in the USA.

Since we have been helping people for all of these years, Kos Tonics™ is our way of helping pets. Click here to start shopping.

Are Kos Tonics an End of Life Pet Product ?

Our K9 Oil Supplements are an all life stages supportive tonic for a dog and a cat. However, as pets age, they definitely need a bit of help. Our formula can assist with that.

Will this calm my dog ?

Yes. Stress relief and anxiety management was an important goal in our research and development process.

Do you have a supplement for a Senior Dog only ?

An additional focus was on elderly dogs with inflammation, joint issues and more. Due to the way key receptors are designed in the body of a canine dog (similar to humans), our product is appropriate for all ages.

Fish Oil Based Supplements for Dogs Frequently Asked Questions

What does it smell like ?

Simply put, it smells a bit like salmon / seafood. Similar to that of a high quality fish oil pill. Since it's all natural from wild caught salmon, it's also free of synthetics. The smell is not overbearing.

Is this a dog flea spray or clean up spray ?

NO. This is intended to be consumed orally. Follow the dosage instructions and mix it with their food (spray) or place it under their tongue (dropper).

Is my dog going to just lay around all day ?

Dogs are complex creatures. They react in different ways depending on their ailments and condition. This will stabilize them and allow them to feel sort of "normal". If they choose to lay around, they will. If they feel like playing again, they will. It is all up to them.

Are your dog supplements gluten free with no preservatives nor artificial flavors ?

YES. Not only is it organic, it's grain free, gluten free, contains no pesticides, no herbicides, no preservatives nor artificial anything. It's all natural. It's 100% USA Made. There is nothing in this that comes from overseas.

Do your supplements work for Cats ?

Yes. Since the biology of a cat is essentially the same as a dog, Our K9 Oil Supplements do work for cats. Use a much smaller dosage.

Why are supplements needed in the first place ?

Senior Cats

This stuff is truly a gift to my cats. I used it for 3 days as the instructions recommended and it has changed everything for the better.

Mary M. (Arizona)

American Pit Bull Terrier

My Rocko was a little rough around the edges. For some reason he was always on high alert and anxious. Within a week he mellowed out and seems much happier.

Jamie G. (Idaho)

German Shepherd

Typical hip issues for my German Shepherd began to present themselves. Although he is aging, thanks to this supplement, he sure does not seem to be in pain.

Cheryl A. (Texas)

Golden Retriever

I think my Golden ate too much plastic from one of her toys and it upset her stomach. I tried this and within days she was back to her usual playful self.

What makes for the best wild caught salmon oil for dogs ? We think it starts with the source.

Properly sourced wild salmon naturally feed on phytoplankton, skrill and shellfish.

Phytoplankton produce oxygen and nutrients which are beneficial to the salmons’ diet.

The source is important when extracting the oil for use in your pets health.

Organic means produced without the use of chemical fertilizers, pesticides, or other artificial

Organic is taken very seriously here at Kos Tonics.

Our products are Organic, Grain Free, Gluten Free, No Pesticides, No Herbicides, Non GMO, 100%
USA Made, High Purity, High Potency.

You may have noticed your dog has slowed down on walks. Your dog may even have difficulty
getting up and down the stairs. Arthritis may be the reason.

Kos Tonics have demonstrated to improve function, reduce inflammation, and slow the
progression of joint damage.

Remember the definition of "organic", this holds true when it comes to vitamins.

Synthetic vitamins are usually created in laboratories, natural vitamins are those that are
found in nature.

The socially accepted point of view is that synthetic nutrients are almost chemically identical
to those found naturally. We do not find this acceptable when it comes to our pets.

What is often undisputed is that the production process of synthetic nutrients is very
different to the way plants, animals, and nature create them.

In addition, it is also unclear how well synthetic nutrients are actually absorbed and used in
the body.

Simply put, our ingredients are all natural.

The simple explanation for the need for dog nutritional supplements is often due to processed pet food.

Ultimately, omega-3 fatty acids are sensitive to heat and light which means that essentially,
by the time processed pet food is packaged, the omega 3’s are basically chemically inactive.

Our natural pet supplements have balanced omegas 3 and 6, vitamins, minerals, DHA, EPA, ETA, GLA and SDA Omegas and everything is 100% USA made.

Basic fish oil for dogs is often the source of two key fatty acids: EPA and DHA. Farm raised
fish and salmon are higher in fat content, exposed to more toxins, fed corn and grains, and
ultimately produce unhealthy omegas. Unhealthy omegas lead to obesity and more.

Our K9 Oil Supplements with wild alaskan salmon oil for dogs also include EPA, DHA, ETA, GLA and SDA Omegas for a more complete solution, and the wild caught source is free of farm raised concerns.

Wild caught salmon is simply the foundation of our formula as several other key ingredients are

As humans, we have enzymes in our mouth that help us break down food. For our pets, those same enzymes and the breaking down of food takes place in the stomach.

An enzyme is basically a catalyst to bring about a specific biochemical reaction.

While our pets love to chew on toys, wouldn't it be best to ensure the active ingredients within a supplement arrive to the immune system quickly and more efficiently through liquid? We think so.

Our liquid supplements are designed to compliment their food. Unlike supplement treats and powders, our aim is to not add more useless calories and ingredients.

A healthy dog should have a strict diet and portions should be controlled.

Long before your dog became domesticated, canines in the wild hunted their own prey. They ate
an entire animal for an optimal diet. They ate the flesh, blood, bones, organs and more.

It is ultimately not recommended to replicate this diet on your own without the proper equipment
and facility.

Finally, the portion of homemade dog food that is cooked has also rendered the omega 3’s
inactive. Omega 3's are sensitive to heat and light.

To avoid light exposure, our packaging consists of dark amber bottles and we recommend to store it in room temperature, cool and dry environments to avoid direct sunlight exposure.
