The Senior Pet Checklist: Subtle Signs of Aging at Home
Our pets age much faster than we do. In veterinary medicine, dogs and cats are generally considered "seniors" once they reach about 7 years of age. While some signs of aging are obvious—like a graying muzzle or sleeping more—many chronic diseases begin with very subtle changes that are easily missed.
Because pets naturally hide chronic discomfort, it is up to us to monitor their daily habits closely. Use this helpful senior checklist to track your aging pet's health at home:
1. Weight & Appetite Changes
What to watch for: Weight loss, muscle wasting along the spine, or sudden weight gain. Also, watch for selective eating or increased fussiness.
Why it matters: Unexplained weight loss in senior cats is a classic sign of kidney disease, hyperthyroidism, or diabetes. In dogs, sudden weight gain or loss of muscle mass can indicate thyroid issues, arthritis pain, or metabolic dysfunction.
Action: Weigh your pet monthly (we do this during every mobile visit!) and log the numbers.
2. Water Intake & Urination Habits
What to watch for: Drinking more water, drinking from unusual places (like leaking faucets or puddles), a heavier litter box, or urinating outside the box.
Why it matters: Increased thirst and urination are primary indicators of kidney disease, diabetes, or Cushing’s disease. In older cats, urinating outside the litter box is often caused by the pain of climbing over a tall plastic box lip rather than a behavioral issue.
Action: Monitor how often you refill the water bowl and inspect the size of wet spots in the yard or litter.
3. Mobility & Stance Changes
What to watch for: Hesitating before jumping onto the couch, difficulty rising after rest, stiffness in cold weather, or a slightly arched back.
Why it matters: Over 80% of senior pets suffer from osteoarthritis. Chronic joint pain can lead to severe muscle loss, depression, and a decline in cognitive function if left unmanaged.
Action: Observe your pet's transition from lying down to standing up. If they "limber up" after walking a bit, they are likely dealing with joint stiffness.
4. Coat, Skin, & Lumps
What to watch for: A dry, flaky, or unkempt coat, new lumps or bumps under the skin, or licking at specific spots.
Why it matters: Senior pets have weaker immune systems and dry skin, making them prone to yeast or bacterial infections. New lumps should always be checked with a Fine Needle Aspirate ($35.00) to rule out cancers.
Action: Run your hands over your pet’s entire body once a week. If you find a new lump larger than a pea, write down its location.
How We Can Help
Preventative senior screening is the key to catching chronic conditions early when they are easiest to manage.
For our senior patients in Luther, Dr. Loomis recommends an annual Senior Health Panel to verify liver, kidney, thyroid, and metabolic health.
