Movement
-
A dog with a concussion will show a difficulty moving by losing balance and showing signs of dizziness. According to the Dog Health Problems Symptoms website, the dog's movement may range from hard to detect, such as slightly staggered walking, or as severe as seizures. The teacup dog and smaller breeds may suffer from concussions easier because of their small size, where falling off of a couch is much harder on their body than on a larger dog.
Body Signs
-
One of the most obvious signs of a serious head injury is bleeding from the nose or ears. The eyes may show signs of head trauma with a change in pupil size. These signs should be noted and immediately discussed with a veterinarian. Blood on the skull may lead to signs of a fracture or other injury causing a concussion.
Shock
-
A dog who has suffered a concussion may go into shock. According to Dogtime's website, shock is likely to occur if a dog is struck by a vehicle or has a traumatic injury. The beginning signs of shock are red gums, shallow breathing, and a rapid heart beat that will become faster as the stages of shock worsen. The gums will change from a bright red in the beginning state of shock to a white or gray color. Immediate veterinarian attention is necessary to treat shock successfully.

Teacup Dog Concussion Symptoms
Teacup dogs are higher maintenance than a larger dog breed. The teacup dog is very small, usually shorter and lighter than a dog in the toy group. According to the Teacup Care website, this type of dog needs more attention than larger dogs, and cannot be left alone as long as others. A concussion can occur at any time, and may not be recognized immediately. It is always important to take an injured animal to a veterinarian for immediate treatment if any symptoms of injury occur.
