A stomach-churning video shows a woman drinking a cup of her dog’s fresh urine while claiming it has cured her acne.

American animal lover Lynn Lew, whose face is caked in heavy makeup during the clip, says that lapping up her mutt’s warm body waste had helped give her skin a natural glow.

In the disgusting footage, she also incorrectly claims that drinking canine body fluids can help cure cancer.

She said: “Many of you have asked me how I always look so good, how my makeup always looks so perfect, or how I always have this natural glow.”

The woman then holds a plastic cup under her dog as the hound cocks its leg against a tree and relieves itself.

After filling up the container with frothy pee, she downs the liquid and even licks the rim of the cup.

She adds: “Until I first drank my dog’s pee, I was depressed, I was sad, and I had bad acne.

“Dog pee also has vitamin A in it, vitamin E in it, and it has 10 grams of calcium, and it’s also proven to help cure cancer.”

Drinking human or animal body waste, known as urine therapy, was practiced in ancient Rome, Greece and Egypt.

However, despite advocates claiming the practice has health properties, experts agree that drinking liquid the body has chosen to expel is potentially harmful.

Joy McCarthy, a holistic nutritionist, told Allure that dog urine could contain toxins or even poisons such as herbicides used for treating gardens lawns.

She said: “Herbicides have been detected in dog’s urine, likely from herbicide-treated lawns, antibiotics, and hormones, so I really don’t know that it’s the safest choice.”

The US army also advises troops to not drink their own urine in survival situations, even if they are dehydrated, due to the liquid potentially containing “harmful body waste.”
