Causes of protruding sternum in dogs:

1. Calcium deficiency: If a dog is deficient in calcium, it will cause osteomalacia. The connection between the chest ribs and the sternum will be indented, causing the sternum to protrude. Supplement your dog with calcium in time and take your dog out to bask in the sun more often.

2. Body weight loss: If a dog is weightless, it will appear that its breastbone is enlarged. You can try to improve its diet.

3. Disease: Generally, a dog’s chest cavity will bulge more than the abdominal cavity, but the obvious bulge may be caused by pleural effusion, cartilage inflammation, hyperplasia, etc. It is best to take the dog to the hospital for a check-up. .
