The Senior Pet Wellness Checklist: What to Monitor After Age 7

Dogs are generally considered senior at 7 years (earlier for large and giant breeds — a Great Dane is geriatric at 6). Cats enter their senior years at 7–10 and are considered geriatric from 15 onward. The biology of aging means that a great deal can change in six months — kidney values, thyroid function, blood pressure, joint mobility, cognitive clarity, and weight can all shift significantly between annual exams. This is why NUZZLE recommends twice-yearly wellness visits for all pets over age 7.

At every senior wellness visit, we perform: (1) A full physical exam with attention to lymph nodes, thyroid gland palpation, cardiac auscultation (murmur grading), abdominal organ size, and joint range of motion. (2) Blood pressure measurement — hypertension is extremely common in senior cats with chronic kidney disease or hyperthyroidism and is a leading cause of sudden blindness. (3) Complete blood count and comprehensive chemistry panel — we track trends in kidney values (BUN, creatinine, SDMA), liver enzymes, glucose, and protein levels over time. (4) Urinalysis with urine specific gravity — urine concentration is one of the earliest indicators of kidney disease. (5) Thyroid level (T4) for cats — hyperthyroidism affects roughly 10% of cats over 10 and is highly treatable.

At home, the most valuable thing you can do is track your senior pet's body weight weekly using a simple bathroom scale (weigh yourself, then weigh yourself holding the pet, subtract). Unexplained weight loss of more than 10% of body weight in a cat is a red flag warranting prompt evaluation. Monitor water intake — a dog or cat who begins drinking noticeably more water (and urinating more) often has kidney disease, diabetes, or a hormonal condition. Note any changes in sleep patterns, nighttime vocalizing (especially in cats), confusion about furniture layout, or getting stuck in corners — these are signs of cognitive dysfunction syndrome, the pet equivalent of dementia, which responds to environmental enrichment and certain supplements.

Joint care becomes increasingly important after age 7. Clinical signs of arthritis include slowing down on stairs, reluctance to jump, stiffness after rest (especially in the morning), and behavioral changes like snapping when touched on the hindquarters. Omega-3 fatty acids (EPA/DHA from fish oil) have the strongest evidence base for joint support in veterinary medicine. NSAIDs are highly effective but require baseline bloodwork and periodic monitoring. We can discuss the full spectrum of options — from weight management and physical therapy to acupuncture and medical management — at your senior wellness visit.
