Dog Cold Symptoms and Quick Diagnosis: A Complete Guide to Runny Nose and Cough

The common cold in dogs refers to acute upper respiratory tract infections. Clinically, it is a febrile illness characterized by nasal discharge, photophobia with tearing, increased respiratory rate, and uneven body surface temperature. It most commonly affects puppies and tends to occur in early spring, late autumn, or during sudden temperature fluctuations.

Causes of Onset

This condition primarily arises from improper care or sudden exposure to cold. Examples include poor kennel conditions, insufficient insulation during winter, or being exposed to cold drafts. Sudden outdoor stays in low temperatures, getting caught in the rain after exercise, or being housed in a damp, cold environment can all contribute to the development of the illness.

Clinical Symptoms

Affected dogs may appear lethargic and indifferent, with partially closed eyes. Appetite is reduced or completely lost. The dog’s skin temperature becomes inconsistent — the ear tips and nose feel cold, while the base of the ears and inner thighs may feel hot to the touch. Conjunctiva appears flushed or mildly swollen, and photophobia with tearing is often observed.

Common symptoms include coughing and serous nasal discharge. The dog may exhibit rapid breathing, intensified vesicular breath sounds, and in some cases, moist rales may be heard. The pulse rate increases to around 80–100 beats per minute, and heart sounds become more pronounced. Body temperature rises, typically exceeding 39–40°C, with irregular fever patterns and frequent chills and shivering. With prompt treatment, recovery is usually swift. However, without timely care, puppies may develop bronchitis or bronchopneumonia as secondary complications.

Diagnostic Methods

Diagnosis can be made based on symptoms such as coughing, nasal discharge, fever, and inconsistent skin temperature, along with the case history. However, it is important to distinguish it from influenza (flu), which is caused by a virus, has a sudden onset, is often epidemic, and presents with high fever. In addition to cold-like symptoms, influenza may also involve conjunctivitis and gastroenteric catarrh (inflammation of the gastrointestinal mucosa).

Treatment Plan

Antipyretic and Analgesic Therapy

The treatment principle involves removing the cause, reducing fever and relieving pain, and preventing or eliminating secondary infections. During the early stages, antipyretic and analgesic agents often yield good results. Subcutaneous or intramuscular injections of aminopyrine solution or antipyrine compound solution can be used. Oral medications such as paracetamol (acetaminophen), phenacetin, somipyrine, or general analgesic tablets are also effective.

Antibiotic Therapy

To prevent or treat secondary bacterial infections, sulfonamides or antibiotics can be administered as necessary.

Preventive Measures

Kennels should be well-ventilated, exposed to sunlight, and maintained at an appropriate temperature. After exercise, dogs should be protected from getting wet or cold, especially during sudden weather changes. Proper care in these situations can help prevent the onset of colds.
