Dog Parasite Infection Symptoms

Dog parasite infections can be divided into external and internal infections. The main symptoms of dog external parasite infections include itchy skin, redness, hair loss, increased dandruff, and in severe cases, skin ulcers, scabs, secondary infections, and inflammation. If a dog has an internal parasite infection, the main clinical symptoms include decreased appetite, vomiting, diarrhea, weight loss, and bloody stools. Sometimes adult parasites can be found in the vomit and feces.

Symptoms of External Parasite Infections in Dogs

External parasites of dogs are usually visible to the naked eye and include fleas, mange mites, ticks, and lice, which attach to the dog's fur. If a dog is infected with external parasites, it may show symptoms such as itchy skin, red and swollen lesions, raised bumps on the skin, and constant scratching.

Symptoms of Internal Parasite Infections in Dogs

Common internal parasites in dogs include roundworms, hookworms, and tapeworms. If a dog has an internal parasite infection, it may exhibit symptoms such as vomiting, diarrhea, weight loss, and in some cases, the dog may scratch its hindquarters. If there are too many parasites, the dog's vomit may contain parasites, adult worms, or eggs.

Note: To prevent dogs from becoming infected with parasites, owners should regularly deworm their pets. It is generally recommended to perform internal deworming every three months and external deworming every month.
