You might not be the type of person to spray your lawn and garden with Roundup weed killer … but that doesn’t mean your dog
Roundup is everywhere. It’s in your dog’s food, in his water and on the ground. Since your dog is exposed to it daily, the million dollar question is … is Roundup safe for dogs?
Research shows it’s not …
What Is Roundup?
Roundup is a herbicide. It’s available in a bottle for home application and it’s also widely used by farmers and by cities for weed control. Its primary ingredient is glyphosate. But it also contains surfactants to help the glyphosate cling to the plants.
Glyphosate is one of the most widely used herbicides in the United States. It’s used in agriculture, on your neighbor’s lawns and gardens, in forestry and even for aquatic weed control.
How Does Glyphosate Work?
Glyphosate is a non-selective herbicide. This means it kills virtually all plants. It does this by stopping an enzyme pathway called the Shikimate pathway. Plants, algae, fungi and bacteria all use this metabolic route to manufacture essential amino acids such as tryptophan, tyrosine and phenylalanine.
Dogs harbor up to a whopping 5,000% more glyphosate than humans.
It also chelates or blocks the plant’s access to vital nutrients including calcium, magnesium, manganese, zinc, iron, copper, nickel, cobalt, boron, molybdenum, selenium and potassium.
Glyphosate basically gives the plant AIDS … it takes away its nutrients and weakens its immune system.
And it’s doing the same to your dog …
How Likely Is Your Dog To Be Exposed To Roundup Or Glyphosate?
Researchers in a study published in JAMA (Excretion of the Herbicide Glyphosate in Older Adults Between 1993 and 2016) tested 50 people in California between 1993-1996 and 2014-2016. They found that the number of people who tested positive for the presence of glyphosate increased … as did the amount of glyphosate.
A lab at University California San Francisco reports that a whopping 93% of humans have glyphosate in their urine. The average sample tested at 3.096 parts per billion (PPB) with children having the highest levels. People living in the midwest and the west had the highest levels.
But the amount of glyphosate in humans is much lower than it is in our pets …
A pilot study by HRI Labs found that the glyphosate levels in dogs are much higher than in humans.
Dogs harbor up to a whopping 5,000% more glyphosate than humans.
So what does that mean for their health?
Roundup And Lawn Chemicals Are Linked To Cancer In Dogs
Roughly half of dogs today get cancer … and that percentage is skyrocketing. And glyphosate exposure could be a big part of this.
A 6 year study from Tufts University School of Veterinary Medicine linked lawn chemicals to a 70% increase in the risk of lymphoma.
A growing body of research shows Roundup is an endocrine disruptor, kills beneficial gut bacteria and damages DNA.
Lawn chemicals have also been shown to increase the risk of bladder cancer in this 2013 study. The researchers in this study also found glyphosate in the urine of dogs living in homes that
Recently, the World Health Organization (WHO) classified glyphosate as a probable carcinogen. Cancer researchers unanimously voted for it. In 2017, California listed glyphosate as a known human carcinogen under its Proposition 65 law.
Ironically, US Food and Drug Administration 2009-2015 Commissioner Margaret Hamberg tries to make us feel better about glyphosate’s link to cancer:
“Sure, you could say that glyphosate causes cancer, of course it does … but only when swallowed in small amounts over a long period of time.”
Yeah, Margaret … that only applies to EVERYBODY!
Is Roundup Safe For Dogs?
That would be a big old no.
In the last 20 years, scientists have documented the health consequences of Roundup and glyphosate and they’ve found that people who are sick have higher levels of glyphosate than people who are healthy.
A growing body of research shows Roundup is an endocrine disruptor, kills beneficial gut bacteria and damages DNA. The following health issues are all linked to glyphosate exposure:
- Alzheimer’s Disease: glyphosate causes the same oxidative stress observed in Alzheimer patients
- Autism: researchers believe the link may be gut dysbiosis
- Birth Defects: glyphosate can block the vitamin A pathways that are crucial for normal development
- Brain Cancer: the risk of brain cancer increases with exposure
- Cancer: cancer rates are much higher in areas where Roundup is used
- Heart Disease: a disruption of biosynthesis of amino acids is linked to heart disease
- Liver Disease: even very low doses of Roundup show a disruption of liver cell function
- Reproductive Problems: glyphosate can impact sperm production and decrease testosterone levels at puberty
Roundup Is Everywhere
Your dog isn’t just exposed to Roundup when he walks on treated grass. Dogs are exposed to glyphosate every day. It’s in their food. It’s in their air. It’s in their water. And it’s in their urine.
With the introduction of genetically modified (GMO) foods, Roundup is now everywhere. It’s estimated we use 20 billion pounds of glyphosate globally … which is 15 times more than when Roundup Ready crops were introduced in 1996. Nearly 75% of all glyphosate used on crops has been used in the last 10 years.
The first crops to become Roundup Ready were cotton, corn and soybeans. Since 1996, more and more foods are becoming genetically engineered. Here are the top 4:
- Corn: 88% of corn grown in the US is GMO or Roundup Ready.
- Soy: 93% of soy is GMO. Soy can appear on labels as lecithin, tocopherols (vitamin E supplement) oils and proteins.
- Cottonseed: 94% is GMO and is used for vegetable oils
- Alfalfa: Nearly all alfalfa in the US is GMO. Alfalfa is found in animal feeds and will accumulate in the tissues of the meats your dog eats.
Apples have recently been genetically modified as well as potatoes, squash, rice, plums, flax, tomatoes, beets and more. Every year, more and more foods will be Roundup Ready. It’s estimated nearly 70% of processed human foods contain GMO ingredients … and percentages for pet foods are likely much higher.
But glyphosate isn’t just in GMO foods …
Roundup is often used on non GMO crops like wheat, barley, oats, beans, peas, flax, rye, buckwheat, millet, beets, potatoes and other crops before harvesting. Roundup is sprayed on these crops (called desiccating or pre-harvesting) to dry them and speed up harvesting.
Even organic crops may be desiccated with Roundup. So even if your food label says
Glyphosate researchers Anthony Samsel and Stephanie Seneff tested a small sample of pet foods for the presence of glyphosate. Every sample they tested contained glyphosate.
Roundup Safety: The Microbiome
Remember that Shikimate pathway that glyphosate destroys?
While your dog might not rely on the Shikimate pathway for his energy, the bacteria in his microbiome do. Your dog’s immune system is formed of trillions of little microorganisms that live on his skin, in his digestive tract and on his body. Collectively, these little communities of bacteria and bugs are called the microbiome. The microbiome is so critical to your dog’s health, it can even communicate with his brain.
Glyphosate destroys these critical bacteria by disabling their Shikimate pathway. Intestinal bacteria produce your dog’s vitamins and short chain fatty acids. They crowd out harmful bacteria and viruses by competing for nutrients. Destroying these friendly bugs can cripple your dog’s immune system … and his health.
And glyphosate can also directly impact your dog. Just as it binds to nutrients and minerals in plants, it will do the same in your dog.
And the worst part is, glyphosate will accumulate in your dog’s kidneys and prevent him from detoxifying. And kidney disease is the second leading cause of death in dogs today.
So, is Roundup safe for dogs?
You be the judge. But avoiding Roundup and glyphosate is impossible for any dog (or human). There are steps you can take to minimize the damage from Roundup … and my opinion is every pet owner should.
