Why Are There Maggots In My Dogs Poop

What Are Maggots?

Before we dive into the details of why there are maggots in your dog’s poop, let’s first answer the question of what maggots are.

Maggots are fly larvae that have not yet progressed into adult flies. Maggots are the product of fly eggs being left behind and soon hatching, and the maggot will typically shed its exoskeleton and transform into a fly within a 2 week period.

Maggots thrive most in warm humid environments, and you most often find them in rotting garbage, animal remains, animal feces, and even animal wounds. Maggots or anything that resembles them are quite startling to come across, so being shocked at their presence is a normal reaction.

You may be surprised to learn that if you see critters that resemble maggots in your dog’s fresh poop, they are likely not maggots at all. If your dog has just passed their stool and there are any crawling worms in it, you are most likely looking at some form of intestinal parasite.

Infected dogs will often pass live worms in their poop if they have fallen victim to a parasitic infection, and some of these worms might look like maggots. Tapeworms are the most common intestinal parasite that are mistaken for maggots in dog poop, but there are many types of worms that can be found in your dog’s stool.

Tapeworms are usually ¼ – ½ inch in length and can sometimes be difficult to see. If you see white specks in your dog’s poop, it is a sign of intestinal parasites.
