Dog Health Symptoms Explained

Dog health symptoms can be difficult to interpret correctly. Many of the same pet symptoms can point to a variety of dog health problems. Understanding canine health involves first learning to make educated guesses when faced with a variety of dog health symptoms. Dog health symptoms manifest through the dog's energy, behavior and physical changes.

Energy Changes

Take note if a dog has a sudden decrease in energy and seems lethargic or disinterested in a favorite toy or activity. If the lethargy persists for several hours despite a nap, your dog may be ill. Low energy can mean that an infection, such as a skin infection, has become systemic. In the summer months, sudden exhaustion can indicate heat stroke or dehydration. A suddenly inactive dog may be experiencing a sudden onset of depression due to pneumonia, fever, a severe allergic reaction or problems with the heart.

Behavior Changes

A dog's disposition generally remains consistent in relation to how he eats, eliminates, and interacts with others. For instance, if your dog generally doesn't whine or cry much, and yet today seems to be complaining a lot, something is probably wrong. If your dog is crying, tensing up, and crouching, he or she may be experiencing pain, usually abdominal. This could be due to bloat or ingesting poison or a sharp object. A dog may have an object stuck in the mouth or throat if he is choking, drooling, gagging, or pawing at the mouth. Convulsions or thrashing about with rigid movements, glassy eyes, or a foaming mouth usually indicate acute distress either from poisoning, possible epilepsy or extremely low blood sugar.

Elimination Changes

Many dog health symptoms become apparent upon investigation of changes in behavior around peeing and pooping. A dog may have a urinary tract infection if she suddenly starts peeing in the house or resists going out to pee. If a dog is scooting on the floor on his rear end or hiding under a bush, he may be constipated or have blocked anal glands and feces stuck in the hair around the rectum. A dog with a kidney or bladder infection may squat numerous times without being able to produce a normal amount of urine, if any. Any straining around elimination indicates a possible infection or blockage.

Physical Changes

Many seemingly minor physical changes can be an indication of a dog health problem. While you can't run to the vet every time your dog's body has a slight change, you can get an idea of his general health by looking at a cluster of changes. A healthy dog's nose and mouth are wet. Sometimes a dog's nose is dry after sleeping but if both the mouth and nose are dry, it can be a sign of distress related to heat stroke or general illness. Any sort of panting or rapid breathing is also a sign of distress. This can indicate pain, pneumonia, heat stroke, an obstructed airway, heart problems or poisoning. If a dog faints, heart disease is also indicated. Bad breath, beyond what results from infrequent tooth brushing, may indicate many varieties of worms, rabies or other infections.
