Ectopic ureters - Tubes from the kidneys to the bladder do not open correctly into the bladder.
Ectromelia - Congenitally absent leg bones.
Ectropion - Abnormal rolling outward of the eyelids.
Ehlers-Danlos syndrome - Connective tissue disease. Produces loose skin that can tear easily. Also called Cutaneous asthenia
Elbow dysplasia - Abnormal development of the elbow joint.
Elbow subluxation - Looseness and/or misalignment of the elbow joint
Elongated soft palate - Abnormally long soft palate extending into the throat causing breathing difficulty.
Endocardial fibroelastosis - Condition where heart muscles develop scar tissue.
Endometritis - Inflammation of the endometrium, the lining of the uterus.
Enlarged Foramen Magnum - Too large of an opening at the base of the skull where the spinal column begins.
Entropion - Where the eyelid rolls inward
Eosinophilic Panosteitis - A painful inflammatory bone disease, generally affecting young dogs, often characterized by increased eosinophils in the blood.
Epidermal Dysplasia - Abnormal development of the outer layer of skin, usually beginning at a young age
Epidermolysis bullosa - Abnormally loose skin with deep, blister-like lesions
Epilepsy - A disease characterized by seizures, convulsions, and/or loss of consciousness. May be managed with various drugs.
Epiphora - A condition where tears do not drain adequately, typically due to excess tear production
Epiphyseal Dysplasia - An abnormal development of the epiphysis, a part of the long bones.
Esophageal Achalasia - Functional stricture or spasm of the muscles of the esophagus where it joins the stomach
Exocrine Pancreatic Insufficiency - A condition in which the pancreas fails to secrete digestive enzymes normally, resulting in diarrhea and weight loss, usually caused by pancreatic acinar atrophy.
Familial Amaurotic Idiocy - Seizures, stupor, blindness, and other neurological effects due to the absence of an enzyme which splits gangliosides, resulting in fatty deposits in the brain tissue. Similar to Tay-Sachs disease in humans.

Fibrosarcoma - Cancerous tumor of fibrous connective tissue.
Fibrous Dysplasia - Condition in which reforming bone is replaced with abnormal fibrous tissue, resulting in bone lesions.
Fibrous Histiocytoma - Cancerous tumor most commonly of the soft tissues, but may affect bone.
Folliculitis - Infection and inflammation of hair follicles.
Fragmented Coronoid Process - Separation of a bony structure of the ulna, affecting the elbow joint. Typically seen in male large breed dogs. Possibly hereditary.

Glaucoma - Optic nerve damage due to increased pressure in the eye.
Globoid Cell Leukodystrophy - Enzyme deficiency ultimately resulting in a loss of myelin, which covers and insulates nerve cells. Results in tremors, muscle weakness.

Goiter - Enlargement of the thyroid gland for reasons other than inflammation or cancer
