Cherry Eye - protrusion of the tear gland associated with the third eyelid.  
Distichiasis -  Eyelashes abnormally located in the eyelid margin which may cause ocular irritation. Distichiasis may occur at any time in the life of a dog.
Entropion - A conformational defect resulting in an "in-rolling" of one or more of the eyelids which may cause ocular irritation.

Panostetis - Generalized inflammation of the long bones. Sudden lameness, usually in a front leg, self limiting. Dogs "outgrow" the condition. Pain can often be greatly reduced by restricting activity, i.e. rest is often the best medicine. Dogs that exhibit signs of lameness should be taken to a vet promptly for diagnosis.
Bloat - A very dangerous condition where even 10 minutes can make the difference between life and death. Gas accumulates in the stomach to the point where it becomes obvious on external examination. The real danger is that the internal pressure cuts off the blood supply to the stomach and other internal organs causing tissue to die and the dog to go into shock.
