How To Help Your Dog Live Longer

Every dog owner wishes to spend as much time with their dogs as possible It is our nature to cherish our loved ones. No one wants to be separated from those whom they care about. I as a dog owner myself wish for my dogs to live a long and healthy life. Here is how you can help your dog live longer:

1. Weight management and balanced diet

Weight management is essential in keeping your dogs healthy. It is a proven fact that a healthy lifestyle leads to a longer lifespan. Generally, dogs with a healthy weight live on average 2 years longer than overweight dogs. Weight management is only possible through a balanced diet. Your dog needs all essential nutrients in order for it to grow healthy and fit. Consult your vet to formulate a healthy diet plan for your dog and avoid feeding it sweet and fat-heavy treats.

2. Regular Exercise

Walks and other activities such as swimming, fetch, and physical training are essential for a healthy lifestyle for your dogs Just like us, our dogs require exercise to keep them physically fit, healthy, and in good condition. Exercise also helps burn excess fat and keep your dog’s heart healthy and strong reducing the chances of heart disease.

3. Routine Vet Checkup

Routine veterinary checkups can help you catch any healthy complication early and promptly deal with it. Vets can guide you and share their professional knowledge and tips for a healthier future. Regular health checkups also ensure your dog’s health stays in optimal condition under the supervision of an expert.

Why Do Small Dogs Live Longer?

Small dogs tend to live longer than large dogs due to several biological and genetic factors. Here’s why:

1. Metabolism and Aging 

Since big dogs have more rapid metabolisms, they complete their growing and aging processes much more quickly than small dogs. This rapid cell division during the growing phase is believed to cause faster cell wear and shorter life spans. Contrary to this, small dogs have slower growth and slower aging; which usually results in a longer life.

2. Strain on Organs 

Since bigger dogs have more body mass, the strain on their organs, especially the heart, is much bigger. In the long run, this increased load can lead to an earlier failure of the organ than in smaller dogs, whose organs do not have such a heavy tax.

3. Genetic Factors 

Larger breeds are more predisposed to specific health problems, such as hip dysplasia, heart conditions, and cancer. These afflictions typically strike and take the lives of big dogs more than they do small dogs. Smaller dogs are less likely to be affected by such diseases. 

4. Energy expenditure 

This means that, because of increased energy output, the bodies of larger dogs work harder at a cellular level to meet basic functions, and this can lead to quicker aging at the cellular level. As a result, their bodies are working at a higher rate and thus wear out faster.

Conclusion

How long do dogs live is a question that worries every dog owner. It is frightening to think that our beloved dogs will one day leave us but it is an undeniable fact and we should work on keeping our dogs healthy and live a happy, loved, and healthy life.
