There are many causes of bone rot in dogs, including: Malnutrition: If your dog's food is lacking in key nutrients such as calcium, phosphorus, and vitamin D, bones may become weak and brittle. Bacterial infections: Dogs can develop bacterial infections. One common disease is called osteomyelitis. This infection can destroy bones and eventually lead to bone rot. Trauma: Chronic or complex fractures, bone defects, and other skeletal injuries may cause bones to become susceptible to decay. Cartilage defects: Some dogs may be born with cartilage defects, which can make bones weak and prone to chipping.
In general, dog bone rot is usually caused by a combination of factors. So it’s very important to take good care of your dog’s diet, health and behavior. If you notice any abnormalities in your dog's bones, you should take him to the veterinarian immediately.
