Megaesophagus
Megaesophagus is basically an enlarged or stretched esophagus. The muscles in the esophagus that should push food along do not work properly. Since a dog’s esophagus runs parallel to the floor, whatever the dog eats or drinks stays in the esophagus, creating pouches or pockets. Food and water then remain there until the dog regurgitates or vomits. Though rare, Megaesophagus can affect any breed or size of dog. Megaesophagus may be congenital(present at birth) or it can be secondary to other disorders such as myasthenia gravis or hypothyroidism. It can sometimes be treated sucessfully with medication, special diets and feeding in an upright postition.

Meningitis
Inflammation of the membranes covering the brain and spinal cord, the meninges. Meningitis can be caused by bacteria, by a virus, by fungi or by a chemical toxin. The most common form of meningitis diagnosed in dogs is steroid responsive meningitis. Symtoms include fever, cervical pain, a stiff short-strided gait and reluctance to walk. It does not respond well to antibiotics, but improves rapidly with Prednisone. Once the dog seems to be back to normal, the dosage of Prednisone can be tapered of and eventually stopped. Relapses can occur, however, and It's not unusual to have to go back on the starting dose. The overall prognosis for this condition is good, with most dogs either recovering completely or at least having manageable disease.

Merle
