Common Behavior Changes in Senior Dogs
Signs of old age in dogs are often exhibited in a range of behavior changes, so if your pup’s getting up there, staying informed about behavior awareness may just have to jump up in priority! You may notice an increase in aging dog anxiety levels, or a slowed once-vibrant energy capacity, both of which can signal the onset of senior years. Your dog acting confused may manifest in forgetfulness or disorientation, while an old dog’s habits or routine might suddenly switch gears, due to declining sensory perception or health issues. Understanding these shifts enables proactive care, tailored to their evolving needs.
Here's a more detailed list of possible things to watch out for from the American Veterinary Medical Foundation (AVMA) who specifies common senior dog behavior changes when cognitive dysfunction may be a contributing factor to dog personality changes:
Here's a more detailed list of possible things to watch out for from the American Veterinary Medical Foundation (AVMA) who specifies common senior dog behavior changes when cognitive dysfunction may be a contributing factor to dog personality changes:
- Increased reaction to strange or loud sounds
- Increased barking
- Increased aggressive/protective behavior
- Increased anxiety
- Acting disoriented or confused
- Increased wandering
- House soiling (“accidents”)
- Changes in sleep patterns
- Less interest in playing
- Repeating the same actions over and over
- Decreased response to voice commands
- Poorer memory and learning ability
If your pet is showing any of these behavior changes or other warning signs of disease, contact your local veterinarian and let them know the specific aging dog behavior changes you've seen. Sometimes, the changes may seem contradictory—such as signs of hearing loss but increased sensitivity to strange sounds.
What Age Is a Dog Considered Senior?
Determining signs of old age in dogs can vary based on several factors. When asking what age is a dog considered a senior, generally, smaller breeds tend to age slower and are considered seniors around 10-12 years old, while larger breeds may reach this stage around 6-7 years old. However, individual factors, such as genetics, health history, lifestyle, and breed, can all influence this transition. Regular veterinary checkups can help pinpoint the specific age-related needs of your furry friend, but in the meantime, try out these tools to better gauge where your pup falls in the journey!

“Behavior changes in [older dogs] can be the first signs of aging. These changes might be due to discomfort or pain (as with arthritis), worsening sight or hearing, certain diseases, or just the normal aging process. A type of brain impairment called “cognitive dysfunction,” which is similar to senility in people, also may be responsible. Stimulating them through interactions can help prevent senility, keep them mentally active.” -- AVMA
Specific Behavior Changes and Their Meanings
Sudden Behavior Changes in Older Dogs
Sudden behavior changes in older dogs probably raise a red flag, and it’s one we wouldn’t recommend ignoring! Senior dog behavior changes might indicate underlying health issues, such as pain, cognitive decline, or sensory impairments, such as vision loss, or hearing loss. An older dog’s personality change could also signal emotional distress or anxiety, so it’s essential to monitor these changes closely and consult with a veterinarian promptly about what to expect with an aging dog. Visiting the vet is crucial if the sudden behavior changes persist, or are accompanied by other concerning symptoms, like lethargy, loss of appetite, or aggression.

Understanding Aging Dog Anxiety
One of the common signs of old age in dogs is a spike in anxiety, and there are certain factors that determine whether your dog will experience it. Physical discomfort caused by age-related conditions, such as arthritis, or a decline in sensory awareness levels, such as vision and/or hearing loss, can result in aging dog anxiety levels. Changes in their environment, routine, or family dynamics can also trigger anxiety in older dogs. Cognitive decline and neurological changes may also spike the nervousness of senior dog behavior. To alleviate aging dog anxiety, provide a stable and predictable atmosphere, maintain a consistent daily schedule, offer comfort and reassurance, and consider veterinary guidance for behavioral interventions, or even medication, if necessary, when anxiety becomes extreme.
How to Support Your Aging Dog Through Behavior Changes
Adjusting Your Home for an Elderly Dog
Elderly dog behavior can mean moving around a little slower, which means making some adjustments to make each movement a little comfier and also diminishing any aging dog anxiety your senior sidekick may be experiencing! Ultimately, making your home more senior-dog-friendly can significantly improve your furry companion’s quality of life.
Consider the following:
Consider the following:
- Install ramps or steps to help them navigate stairs more comfortably.
- Provide supportive bedding with extra cushioning, to relieve pressure on achy joints.
- Remove obstacles and hazards to prevent accidents and falls.
- Ensure easy access to food, water, and bathroom areas.
- Adjust the lighting to aid their vision, especially in dimly lit areas.
When to Seek Help: Behavior Changes That Need Attention
While some senior dog behavior changes are just natural signs of old age in dogs, others may signal underlying health issues, or require professional intervention. Normal behavior changes in older dogs include mild decreases in activity levels, minor changes in appetite, and occasional forgetfulness. However, elderly dog behavior changes such as sudden aggression, excessive lethargy, persistent anxiety, drastic changes in appetite or water intake, and disorientation, such as your dog acting confused, warrant prompt veterinary attention. Regular communication with your veterinarian ensures early detection and proper management of age-related issues.
