How long does a dog’s cold and cough usually take to heal?

Different dogs take different times to improve from a cold and cough, depending on their physical condition. Strong, resistant dogs usually recover in about 2-3 days of medication, but if immunity is weak it may take 5-8 days to fully heal. A cough from a cold is usually not hard to cure, but the owner must treat actively, keep the dog warm, and use pet cold medicine when needed, so the dog recovers quickly.
