some of the main reasons why golden retrievers seem to be dying younger than their life expectancy in recent years:
Cancer - Goldens have a high risk of cancer, especially bone cancer, lymphomas and mast cell tumors. As many as 1 in 3 goldens will die of cancer. Better breeding practices could help reduce this risk.
Obesity - Many pet goldens are overweight or obese due to overfeeding and lack of exercise. Extra pounds put extra stress on joints and organs, increasing risks for conditions like arthritis, heart disease, etc.
Allergies - Food allergies are common in goldens and can lead to skin infections or complications if not properly managed. This contributes to lower quality/length of life.
Hip dysplasia - Improperly formed hip joints can cause pain and mobility issues. Poor breeding practices have led to increased rates of hip dysplasia in some golden lines.
Infectious diseases - Parasites like heartworm and tick-borne illnesses like Lyme disease can seriously impact golden health if not prevented with medications.
Lack of vet care - Without thorough annual exams and preventative care like dental cleanings, hidden problems may be discovered too late to treat effectively.
Poor breeding - Unscrupulous or inexperienced breeders prioritize looks/profit over health testing can produce dogs with genetic issues.
Focusing on responsible breeding, early socialization, lifelong medical care and weight management can help golden retrievers live healthier, longer lives.
