Whether you’re in biology class or ordering a piece of rib at a restaurant, you’ve would recognize a rib cage. A rib cage gives your dog’s belly its barrel-shaped chest, and I’ve often heard people wonder how many ribs does a dog have?
All dog breeds have 13 pairs of ribs, they all connect. Nine of the ribs are to the dogs’ sternum (sternal) and four to the cartilage in the rib (asternal), giving a total of 26 ribs.
If your dog breathes in and out, you may have noticed his rib cage. Your dog’s ribs give structure and protection to vital parts, including the lungs and heart, structure, and protection. It acts as a safeguard for your dog’s organs against any kind of external force, blows, or attack.
Floating Ribs in Dogs
We refer to the first of the seven pairs of your dog’s ribs that are directly connected to the breastbone to a true rib, and they connect the five other pairs to the dog’s sternum by cartilage.
These are false ribs. The final two ribs are called swimming ribs. They may see these in dogs as a bony protrusion in some dogs; cartilage covers the swimming rib.
Some think these floating bones are an indication of a broken rib, but this is not always the case. However, it’s always best to exercise caution if you are worried about a broken bone.

The Function of the Dog’s Rib
The rib cage resembles the bars in a steel cage. The rib cage keeps your dog safe by protecting his major organs such as the kidneys, spleen, stomach, heart, and lungs.
A dog’s rib cage also offers many powerful and malleable muscles that support other areas of the body like the chest, spine, and upper abdomen from external injury and damage.
The Rib Structure of the Dog
A Dog’s bones are made up of strong, mineralized tissue that provides structural protection for the body. Ribs also indicate your dog’s weight, you can check by putting your hand on the rib.
If the ribs are easy to feel, it means that your dog’s weight is normal. If it doesn’t and you feel a layer, it could indicate fat and a sign of being overweight.
All dogs have bones of different sizes. For example, dogs such as Chihuahuas have the same bones as a Great Dane, but the size and bone shape of their bones are very different. Dogs, unlike other animals, have a variation in the amount and composition of their skeleton.
- The skeleton is divided into three standard subunits:
- Appendage skeleton bones and others of the extremities.
- Axial skeleton: spinal and skull bones, ribs, and sternum
- Visceral skeleton: bone that is part of an organ.
- A skeletal comparison of humans and dogs
Dogs have between 319 and 321 types of bones in their body, while people have only 206 bones. Long-tailed dogs have more bones when compared to a dog with a shorter tail, all dogs will have disconnected shoulder bones that allow them to move above people more often.
It can anything up to 18 months for a dog’s skeleton to mature. However, the maturation period depends on growth and your dog’s size. For example, the skeleton of a toy breed will mature in a couple of months, while bigger breeds of dogs can take from fifteen to eighteen months to mature. In humans, bones mature between the age of 25 and 30 years old.
Bone Cancer Can Occur in the Dog’s Ribs
There are several health-related problems that occur within a dog’s ribs, such as osteosarcoma (bone cancer) is more aggressive and forms a fatal form of rib cancer. It is a problematic condition, especially as it can spread throughout the body. It is therefore important that you check your pet and have regular veterinary checkups.
If this form of cancer spreads to another part of the dog’s body, such as the lungs, it could cause a dog to have severe difficulty breathing. Surgical removal is usually the only treatment option.

Broken Ribs in a Dog
Typically, dogs suffer a fracture to their ribs as the result of an automobile accident or violent treatment because the ribs cannot endure such a powerful hit. When dogs develop a fracture, they need immediate and ongoing care to treat the fracture. Less movement and adequate medical care can speed the healing process, or complications may develop.
Broken ribs can directly affect a dog’s lungs which can cause difficulties in breathing as a result of a collapsed or punctured lung, so it’s vital that you bring your dog to a vet if there is a fracture.
A broken dog bone, especially in the ribs, is a problem and will require immediate veterinary attention. Rib fractures are not only very painful but there is the potential for sharp shards of ribs to puncture a lung.
Vets will note that any signs your dog is suffering from an accident can show a broken rib. If your dog has a traumatic accident, e.g. For example, if a car hits him, it’s a better idea to take them to the vet for evaluation, even if he doesn’t appear to be in any pain.
Your vet will start by fully assessing your dog’s general condition. Look at his chest to identify any open wounds, covering them with clean gauze. Then wrap your dog’s entire chest in sterile, torn sheets. Make the cloth firm, but not so tight that as it might interfere with a dog’s breathing.
Some owners might notice that a dog’s chest is swollen. If the bulge is tight, it could be the end of a broken rib. It’s possible that a broken rib punctures a lung. If this has happened, you may hear a sucking-like sound from a dog’s chest.
These are emergencies and owners should contact their veterinarian immediately. If your vet notices that the rib fracture is severe, he may need to have it surgically repaired. We can repair most breaks with pins and wires connected internally or externally through the dog’s skin.
When it’s time to bring your dog home, Experts recommend that you keep your dog quiet and encourage him to rest. Your dog may prefer to sit or lie down in certain positions when his ribs are healing.
