Since our dogs are part of the family, I treat them like my children. At the first sign of a symptom, I act on it immediately. And when the vet is needed, I would call our vet (fortunately one of our 2 vets make home service). Like last week, Pipoy, our 3-year old hyperactive pug was emitting a sound like coughing. Our housemaid said that Pipoy may have the colds. The vet came and had prescribed medicine. Another time, one other dog, Tisoy, our 8-year old spitz, has rashes in his tummy so I again summoned the vet. It is not good to ignore the symptoms. Do not wait until the problem gets out of hand.
