What should I do if my dog has red spots on its body?

Red spots on a dog's body may be caused by external parasite infections, mosquito bites, allergies, eczema, fungal infections, and other reasons. If you find red spots on your dog, it is essential to handle them promptly. You can consult an online pet doctor for medication or take your dog to a pet hospital for inspection and treatment. Do not use drugs randomly to avoid delaying treatment and causing irreparable consequences.

1. External Parasite Infection

If the owner does not give the dog regular external parasite prevention, the red spots on the dog's body may be caused by bites from external parasites such as fleas. Check carefully by lifting the dog's fur to see if there are fleas or flea excrement. If any abnormalities are found, it is recommended to consult a pet doctor in a timely manner and choose appropriate parasite control drugs for the dog.

1. Mosquito Bites

If your dog suddenly develops red spots after playing outside, it could be caused by mosquito bites, especially if the dog often plays in grassy areas. In this case, reducing the frequency of outdoor play will generally cause the red spots to disappear gradually.

1. Allergies

If a dog develops a widespread rash accompanied by itching after eating a certain food or receiving a vaccine, or within half an hour after taking a certain medication, it is likely caused by allergies. This situation can be dangerous, and it is recommended to take the dog to a pet hospital immediately for injection of desensitizing agents to avoid potential life-threatening risks.

1. Eczema

If a dog lives in a damp environment for a long time, it can easily reduce its skin's resistance and develop eczema, resulting in red spots and severe itching. To treat eczema, ensure a dry environment. If the eczema is localized, it will gradually improve with environmental changes. If it covers a large area, shave the dog's hair clean, use specialized shampoos, and take oral antibiotics if the infection is severe.

1. Fungal Infection

If a dog has red spots, hair loss, crusting, and itching, it may be caused by a fungal skin disease. It is recommended to take the dog to a pet hospital promptly to determine the specific cause and treat accordingly.
