Common signs of aging in dogs and cats include gray, thinning hair, diminished hearing, and declining eyesight. Like for humans, these can all be normal parts of the aging process and are typically nothing to worry about, although some senior pets never experience these changes.

What is possibly normal

Several health issues can affect older pets and bring changes to their behavior and activity levels. These include arthritis and cognitive dysfunction.

Symptoms of arthritis and cognitive dysfunction include having accidents in the house, less interaction with humans, an increase in aggression, an increase in barking or meowing, mobility issues, changes in sleep, poor problem solving, avoiding running or jumping, or favoring a leg.

However, these symptoms can also be attributed to concerns that are common in older dogs and cats. That’s why it’s important to bring seniors to the vet for exams twice a year. Your vet will be able to help assess if there’s a serious underlying health condition causing your pet’s symptoms.

When to see the vet about your senior pet's signs of aging

If your pet suddenly loses weight or their appetite, schedule a vet visit immediately. Increased aggression or unusual behavior warrants a veterinary check-up as well. Additional things to look out for are abdominal swelling, incontinence, seizures, bleeding gums, labored breathing, lumps and bumps, prolonged diarrhea and/or vomiting, and other skin issues.

Unfortunately, cancer is accountable for nearly half of dog deaths and a third of cat deaths. Other common medical conditions that affect seniors include heart disease, diabetes, kidney disease, and liver disease. We want to catch disease early so we can help your senior pet maintain good health. Some things are unpreventable, but there are often steps you can take to help reduce the progression. Don’t hesitate to reach out to a vet if you have cancer.

When should I be concerned about my senior dog? How do I know if my cat is nearing the end of life?

These issues can be super tough to determine. Using a tool called a quality of life scale, a form of objective journaling, can help. Regularly record observations of your pet’s appetite, breathing, care, demeanor, energy, and family interactions to see if their symptoms are improving or declining. This can help you and your vet evaluate your pet’s condition and create a baseline for their healthcare needs.
