We are also now diagnosing and treating disease such as hypertension, glaucoma, inflammatory bowel disease , chronic liver disease , and cushings disease just to name a few. Dogs and cats may also develop nerve disorders as they age. Repeated episodes of stumbling, for example, may indicate myelopathy - a dysfunction of the spinal cord and its associated nerves. Cats and dogs may develope arthritis on the spine. Nerve disorders can also arise when tumors or ruptured vertebral disks impinge on nerves.
Tumors are more common in the older rather than in younger pet.
But not all tumors are life-threatening. Many older animals develop benign skin tumors, which veterinarians can easily remove. As with all medical conditions, however, early detection and treatment of tumors offers the best hope for a favorable outcome.
