The first instinct is to talk to your veterinarian. During the annual visit, for example, your dog will be weighed and you will be told whether his weight has changed compared to previous years and if everything is fine, or not.
Then, you will easily find on the internet the ideal weight of Médor according to his breed. Once it reaches more than 10% of its average reference weight, it's a bad sign!
Finally, dog overweight is easily detectable with the naked eye:
the spine, ribs, and pelvic bones are not visible
folds of fat around the neck or at the base of the tail
The size is not marked
fat cover on the belly
Beyond a few unsightly bumps, which will not particularly affect them from a psychological point of view, the health risks are high.
heart and respiratory problems, easily detectable during physical activity
difficulty moving or even rupture of the cruciate ligaments
hypothyroidism
reduction in life expectancy
osteoarthritis and other joint problems
urinary infection, kidney failure, digestive problems, diabetes
difficulty coping with heat
tendency to develop tumors
herniated disc
This is of course not an exhaustive list.
Identifying a health concern
Your dog is not necessarily a glutton in need of sport, he may be suffering from a disease causing him to be overweight. First, consult a veterinarian to make a diagnosis.
Take care of his diet
Food is a key factor in keeping your dog balanced.
If you feed your dog the household diet, make sure that the doses are adapted to his breed and his habits.
If you prefer a pack of kibble or a box of pie, you have to read the compositions carefully! The important thing is a good protein intake, limiting carbohydrates and other unnecessary additions as much as possible. Do not give more than the recommended dose.
Lie in his basket all day, your dog will not lose weight by only running up to his bowl...
Your companion should take a walk for at least 30 minutes every day. If he is not a great adventurer, go for a walk with his peers, maybe he will try to run a little more in their company! Throw the ball at him, create interaction every day to encourage him to exercise!
