Leonberger: Adult and senior changes
For an adult or senior Leonberger, a change from the dog's own normal baseline deserves more attention than a generic age expectation. Use the individual dog's age, comfort, and recovery to set the pace. Compare movement, appetite, sleep, interaction, and body condition week to week; make one low-impact change and record the result. Compare with the dog's own recent baseline and make one low-impact change before judging the result.
What a change may be telling you
Leonberger's weight is recorded as 110-170 pounds (male), 90-140 pounds (female). Here, that matters because it gives context for the individual dog's body condition, but not a target by itself.
Compare the dog with its baseline
- Compare movement, appetite, sleep, interaction, and body condition week to week; make one low-impact change and record the result.
- Use the weight (110-170 pounds (male), 90-140 pounds (female)) as context, then measure the individual dog's trend rather than changing the plan from the reference alone.
- Compare with the dog's own recent baseline and make one low-impact change before judging the result.
Arrange veterinary review if
Book a veterinary assessment for persistent pain, reduced mobility, weight change, confusion, or a sudden behaviour shift.
If this may be a health problem
This page is not a diagnosis or treatment plan. Do not change food, medication, exercise, or care for an individual dog based on this page alone; contact a veterinarian for symptoms, pain, weight change, skin changes, persistent behaviour change, or any urgent concern.

Grooming: Leonbergers shed a lot'and twice a year, they shed even more. A Leo should be brushed every day, especially in the areas of his body that tend to mat: the long hair behind the ears and on the backs of the legs. A more thorough grooming should be done once a week'and given the breed's size, this will take a fair amount of time. Leos have a thick, full outer…

Exercise: If you live in a city apartment or a house on a small, suburban lot, this may not be the breed for you. Adult Leonbergers are generally calm and subdued, but they still need to have some vigorous exercise once a day. Puppies and adolescents are active and exuberant. Adult dogs can benefit from jogging or hiking with their owner or keeping pace alongside a…

Training: Leonbergers are very large and strong. In addition, puppies and adolescents have loads of energy and are extremely enthusiastic. With these facts in mind, proper training of the breed is essential. Leo puppies should be socialized by being gently exposed to a wide range of people, animals, and settings before the age of 20 weeks. Group obedience classes…
