Canine longevity depends on many factors, such as quality of life, race or dietaverage expectation is estimated between 10 and 13 yearsAccording to the data of World Animal Health Organization (WHO), Although there are exceptional cases, such as dogs that can more than 20 yearsThe variability in the age of dogs is very marked.
A recent study has evaluated this through a sample 584,734 pure and mixed breed dogs, the impact of genetics, age, size and even health insurance on your life expectancy. 18 organizations took part in this research, including rehabilitation and welfare organisations, breed registries, pet insurance companies, veterinary corporations and university veterinarians.
“Older animals often don't have pet insurance.”
Data on pet insurance have attracted the most attention from researchers. “Older animals are often not insured,” the researchers explain. Additionally, some policies provide life coverage only up to a certain age. This bias also takes into account that not all dogs are insured regardless of age.
The results of this research confirmed that, it is not possible to determine diseases, euthanasia or deaths from natural causes as direct risk factors for premature death. However, when compared they obtained results race, body size, sex, or cephalic index, Based on these factors, scientists claim to be able to “identify groups and/or lineages that require further consideration.”
One of these considerations is the preference or fashion for certain breeds. This explains why on many occasions the breed or size of dogs is put before animal welfare. Furthermore, previous studies have confirmed a long life expectancy In mixed breed dogs compared to pure breed dogs.
The study included 44% to 87% of crossbred animals rehomed in the United Kingdom
However, this publication confirms more hope in purebred dogs. 47.1% survival, while only 25.8% had a shorter life span than mestizos and 27.1% had no significant difference. For a more comprehensive analysis, this study includes Between 44% and 87% of animals Mixed breeds moved to the United Kingdom.
Although according to this study purebred dogs live longer, it has also been found Variability between breeds, For example, average estimates for West Highland White Terriers are reported at 12.7 and 13.5 years of age, while for Rottweilers they are significantly lower at 8.0 and 8.4 years of age.
Although these findings provide valuable information about the longevity of the breed, it is important to recognize that the population of purebred dogs and therefore their population management is affected by this. environment and space, In this case, the analysis shows a greater trend for purebred breeding in the United Kingdom.
The increase in demand for purebred dogs as well as impulse purchases has resulted in puppies becoming a lucrative business, without considering the welfare of the dogs, Furthermore, according to those responsible for the study report, there has been an increase in the rate of dogs suffering from physical and psychological problems promoted by improper breeding.
For this reason, those responsible for this study suggest that the longevity advantage presented in mixed breed dogs in previous studies may be due to the following reasons: homozygous lack of deleterious genesWith non-genetic differences between and within pure and crossbred populations.
The burden of disease in most purebred populations has become one of the most important issues in dog welfare.
“As a result, the burden of disease in most purebred populations has become one of the most significant issues in dog welfare. “It is imperative that future discussions be open and multidisciplinary, as they have important implications for the quality of life and longevity of dog breeds, as well as the ethics of breeding practices,” the researchers concluded.
