“Trying to identify this as I just took the dog to hospital for what looked like a seizure and found this where he was”, writes this reader in her submission regarding the dark brown worm-like organism pictured below. “Scared this may be the cause. What is it?” Right off the bat, we will have to inform our reader that we can unfortunately not identify this worm, given its possible connection to her dog’s health issue. In fact, we never identify organisms that could be the cause of a health problem, as those situations are always medical in nature, and since we are not medical professionals, we are neither qualified nor legally able to provide such identification, as doing so would be tantamount to giving a diagnosis.
