All living things age with time. Unfortunately, pets age more rapidly than humans do. Most dogs and cats are considered "senior" at 7 or more years of age. Many diseases and behavioral problems only become apparent with age. Arthritis, dental disease, cancer, kidney disease, liver disease, heart disease, thyroid or adrenal problems, and diabetes are among the most common problems in older pets. The good news is that dogs and cats are living longer and healthier lives now than ever before, because many problems in older pets can be prevented, treated, or managed.

Some of the warning signs that a pet owner should watch for include change in food or water consumption; change in weight; change in activity level; difficulty in rising, walking, or climbing stairs; abnormal urination or defecation; unusual body odors; lumps or masses in or under the skin; coughing or sneezing; increased panting, wheezing, or difficulty breathing; vomiting or diarrhea; or a change in behavior.

Some steps that can be taken by a pet owner to assure the continued good health of their senior animal include, but are not limited to, more frequent veterinary health exams (at least twice yearly); regular blood, urine, and fecal testing; vaccination against appropriate contagious diseases; heartworm testing and prevention; and finally, feeding of a diet specially formulated for senior pets or a therapeutic diet to help manage specific medical conditions. Consult your veterinarian for specific recommendations for your individual pet.
