A study conducted by the University of Sydney found that a Labrador of certain colors had a shorter life expectancy and also had more health problems.
They observed 33,000 Labradors in the United Kingdom, where they evaluated the dog’s electronic data as part of the VetCompass program for the University.
Labrador with chocolate color had a short life of 10%, shorter than their golden and black counterparts (who lived an average of 12.1 years).
Those chocolate fur puppies also have double chances of ear infection and are also prone to suffer from a condition known as pyo-traumatic dermatitis.
Professor Paul McGriffy, of the University Department of Sciences said: "The relationships between the color of the coat and the disease can be an inadvertent consequence of the reproduction of certain pigments.
"Because the color of chocolate is recessive in dogs, the gene of this color must be present in both parents for their dogs are chocolate." Therefore, breeders who focus on this color may be more likely to breed only the Labrador that has the chocolate gene fur.
‘It may be that the resulting reduced gene pool includes a higher amount of genes conducive to ear and skin conditions.’
As we know from the amount of purebred dogs, keeping any gene pool small makes puppies more prone to diseases and health problems.
Since the Labradors are breed prone to obesity, ear infections and joint conditions anyway, it is not good to prioritize the colors
over health when getting a puppy.
There are many dogs in rescue homes that need someone to take care of them, but if you insist on getting a dog from a breeder, take the proper precautions.
Ensure your dog is vet-checked from birth, and then frequently as it grows up, which seems like clear information but is frequently ignored. A whopping 8.8% of Labradors are obese, so maybe invest in some special food too!
