"The evidence is overwhelming," says Dr. Emily Redmond, a veterinarian who's been documenting adverse reactions for over a decade.
"We're seeing patterns that can't be ignored... And for many dogs, the consequences have been fatal."
Her findings are devastating:
In August of 2018 she conducted a survey (Project Jake) and examined the use and safety of these treatments given to dogs.
There were a total of 2,751 survey responses, and 67% of those (1,843 dogs) reported some form of side effects on their dogs.
The EMA (European Medicine Agency) also investigated the side effects of popular flea and tick treatments on dogs, and what they uncovered is alarming:
Seizures: Dogs on NexGard, Bravecto, Advantix and others face significantly higher rates of seizures - with some previously healthy dogs experiencing them after just one dose.
Neurological Damage: The FDA (Food & Drug Administration) issued warnings after mounting evidence of dogs experiencing tremors, loss of coordination, and permanent nerve damage.
Skin Reactions: Up to 20% of dogs develop severe itching, hair loss, chemical burns, or raw patches - the very problems these treatments were supposed to prevent.
Organ Damage: Studies show that the harsh chemicals in these treatments accumulate in the liver and kidneys, causing long-term damage that shortens lifespans.
