Dogs are your true family members. It will be heartbreaking to say goodbye if you lose your pet. Isn’t it? If you need a good companion for the rest of your life or don’t want to say goodbyes to your canine friend, choose a long-lived dog breed.

Does Breed Affect Lifespan?

Many factors determine the lifespan of your canine friends. The dog average lifespan not only determined by the breed , but other factors too. A healthy diet, when combined with regular veterinary care, can increase the lifespan of your dogs. Crossbreed dogs can live longer than inbred ones. It is because inbred dogs can have the risk of carrying genetic illnesses that will be specific to related breeds.

Crossbreeds (of at least two species) tend to have lesser health issues and more life spans than inbred ones. According to some studies, breeds with an effectively larger population size had common survival space (i.e.) three to six months longer than breeds with smaller populations. This indicates that the measures that come in for genetic diversity might affect the species’ lifespan. 


If you wish to choose your life-long companion, go for a reputable breeder, and take health tests that help reduce genetically inherited diseases in your canine friends. Choose mixed dog breeds rather than purebred varieties for a longest living dog for your life-long companion. Don’t prefer a giant breed if you are looking for a life-long companion. I prefer smaller dogs as long living pets because they live longer than large dog breeds. Last but not least, exercising together with proper diet can help them live a longer life as obesity is one of the worst things that kills people..
