The age at which the dog can be considered elderly varies according to several factors including size:
The most obvious signs of a dog's old age are:
The hair turns gray on the muzzle and around the eyes
The dog tends to decrease physical activity and consequently gain weight, the nails become brittle, the skin becomes thinner and is more exposed to bruises and wounds
May become slightly incontinent
Breath becomes heavy
Sensory perception decreases
There are also noticeable changes in behavior
Particular attention should be paid to eyesight for particularly elderly dogs.
The walk must be short and controlled by the leash.
Finally, the weight must always be checked: sudden increases or decreases could be the signals of possible pathologies.
