When keeping a dog, it is important to observe closely for certain signs. These signs may indicate that the dog has a short lifespan. The first sign is excessive tear stains, which can be a result of excessive salt intake and may lead to kidney failure.

Controlling salt intake through a low-salt diet is essential. The second sign is excessive body fat, which can cause various health issues in the dog's old age. Maintaining a healthy weight is crucial. The third sign is poor coat quality, which can be a result of inadequate nutrition.

Feeding the dog a nutritious diet and offering food that promotes healthy coat growth is recommended. The fourth sign is frequent constipation or painful defecation, which requires veterinary attention. The fifth sign is a lack of muscle and visible ribs, indicating a lack of nutrition.

Lastly, dogs with a short lifespan are prone to frequent illness and should have their immune system strengthened through regular exercise and good nutrition.
