Dogs can’t tell us when something is wrong, so it’s up to us as pet owners to recognize the signs of infection early. Infections can occur in various parts of a dog’s body, such as the skin, ears, respiratory system, or internal organs. Early detection and treatment are crucial for a full recovery. This guide explores common infection symptoms in dogs and offers practical advice for identifying them.
1. General Signs of Infection
Regardless of the infection's location, some symptoms are common across different types of infections. Look for these signs:
- Fever: Elevated body temperature is a common sign of infection. Dogs with a fever may appear lethargic or refuse to eat.
- Loss of Appetite: A sudden decrease in appetite can signal an underlying infection.
- Behavioral Changes: Dogs may become withdrawn, irritable, or display unusual behaviors when they’re unwell.
- Lethargy: Reduced energy levels or reluctance to play can indicate illness.
If your dog exhibits these symptoms, consult a veterinarian promptly.
2. Skin Infections
Skin infections are among the most visible and often caused by bacteria, fungi, or parasites.
Symptoms of Skin Infections:
- Redness or swelling.
- Pustules or scabs on the skin.
- Excessive scratching, licking, or biting.
- Hair loss or bald patches.
Common Causes:
- Allergic reactions.
- Flea infestations or tick bites.
- Cuts or wounds becoming infected.
Use flea prevention treatments and regularly inspect your dog’s coat for abnormalities to prevent skin infections.
3. Ear Infections
Ear infections are frequent, particularly in breeds with floppy ears, like Cocker Spaniels or Basset Hounds.
Symptoms of Ear Infections:
- Head shaking or tilting.
- Excessive ear scratching.
- Redness and swelling inside the ear.
- Unpleasant odor or dark discharge.
Common Causes:

To prevent ear infections, clean your dog’s ears with vet-approved solutions and avoid inserting objects into their ears.
4. Respiratory Infections
Respiratory infections can range from mild to severe and may affect the upper or lower respiratory tract.

Vaccination and avoiding high-risk environments can reduce your dog's chances of respiratory infections.
5. Gastrointestinal Infections
Gastrointestinal infections can result from bacteria, viruses, or parasites.
