Dogs can be hosts to various types of worms, including roundworms, tapeworms, whipworms, and hookworms. These parasites can cause serious health issues, ranging from digestive problems to more severe conditions like anemia and malnutrition. It’s essential for dog owners to regularly monitor their pets for signs of worm infestations, which may include weight loss, vomiting, diarrhea, and a bloated abdomen.
