I found a tiny worm in my bathtub. Could it be from my dog or drain?

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 80 lbs

I found a worm wriggling in my bathtub. It's approximately 1.25 to 1.5 inches long. It is so thin it is hard to see, even if I'm wearing my reading glasses. It is thinner than the thread I use when I'm sewing. I wonder if it came from my dog? Or did it climb up the drain? Or did it fall off my foot? Or what?

Unfortunately, without being there, it would be hard to tell where the worm came from! If you suspect it may have come from your dog, bringing in a sample of his stool to your local vet can help them test for parasites such as worms and parasite eggs, and provide you with medication to treat it. If you see visible worms coming from your pup when he defecates, this can also indicate that he has a parasite infection. if you suspect the worm came from you, it would be best to seek the advice of a human medical doctor.
