A dog is generally considered to enter its "senior" years at around 7 or 8 (earlier for large breeds). Naps may get longer, but exercise remains the best medicine against the effects of ageing. The goal is to move from performance to maintenance.
How age affects the body
Over the years, three major changes affect a dog's mobility:
- Sarcopenia: A natural loss of muscle that makes the joints less stable.
- Arthritis (osteoarthritis): Wear of the cartilage that causes chronic inflammatory pain.
- Reduced cardio-respiratory capacity: The heart and lungs cope less well with intense effort.
Stopping all activity is the worst mistake: it speeds up muscle loss and makes joint stiffness worse. The golden rule is: "Movement is life".
Adapting the exercise routine
1. Choose regularity over intensity
Go for three 20-minute walks on flat ground rather than one long, hilly hour-long hike. Avoid throwing games (ball, frisbee): the sudden stops and jumps are extremely harmful to worn joints.
2. Swimming and hydrotherapy
If the water is warm enough, swimming is the perfect exercise. The water supports the dog's weight, so muscles and cardio get a workout with no impact on the joints. It is the go-to activity in rehabilitation.
3. Mental stimulation: "Nosework"
When the legs get tired, the nose still works perfectly. Treat-hunting games and gentle tracking tire your senior dog out in a healthy way without straining their body. It is an excellent way to keep their mind sharp and stave off canine cognitive decline.
Warning signs to watch for
Watch your dog during and after exercise. If they limp, struggle to get up the next morning, suddenly refuse to jump into the car or get unusually out of breath, it is time to reduce the intensity and see your vet.
Tracking longevity with Son Espace Santé
The app is a valuable tool to support your companion in their later years:
- Mobility Log: Each day, rate from 1 to 5 how easily your dog moves around. Useful to see whether a new treatment or supplements (glucosamine, omega-3) are working.
- Medication Log: Set reminders for pain-relief treatments or heart support medication.
- Progress Album: Use photos to spot any changes in posture (hunched back, lowered head).
- Working with your Vet: Share your notes on your dog's sleep quality and appetite for the best possible senior health check.
Staying active as they age is the secret to a happy old age. By matching your pace to that of your old friend, you will still enjoy many happy moments together.
