How to Judge if a Dog has Parasites

** External Parasites **

These parasites can be seen with the naked eye, and common ones include fleas, mange mites, ticks, and lice. They attach to the dog's fur, and once parasites are present in the dog's body, their appetite becomes large. However, the dog's absorption of nutrients is much worse than that of a normal dog, so the dog becomes thinner. Some dogs may have loose stools or diarrhea, and internal parasites can also cause dogs to exhibit the behavior of rubbing their bottoms. If there are too many parasites, the dog may vomit, and the vomit may contain parasites, adults, or eggs.

1. Fleas

Fleas are one of the most common external parasites on dogs. If not controlled, they can even cause acute eczema and pus-filled lesions.

2. Mange Mites

The development of mange mites goes through four stages: egg, larva, nymph, and adult, all of which occur on the host. The harm of mange mites lies in their ability to cross-infect both dogs and their owners, with an incidence rate of about 25-30%. Usually, once a dog infected with mange mites is treated, the owner's condition improves rapidly.

3. Ticks

Also known as dog ticks, grass ticks, and bush ticks. Ticks are the fastest-spreading parasites among diseases.

All of these parasites are visible to the naked eye and attach to the dog's fur.

** Internal Parasites **

The most common internal parasites are roundworms, tapeworms, and hookworms. Infection can cause weight loss, loss of appetite, and severe cases can even cause vomiting, with parasites, adults, or eggs in the vomit. In addition, there are also coccidia and trichomonads, which can easily cause diarrhea or even bloody stools in pets after infection.

Both external and internal parasites can cause significant health problems for dogs. Pet owners must pay attention to regularly deworming their dogs and keeping them clean.
