Bone Anatomy in Dogs and Cats

Exploring Bone Differences

Comparing bone structures across species:

• Dogs: Approximately 319 bones
• Adult Cats: 230 bones
• Humans: 206 bones

While bone numbers vary, some fuse together as animals grow.

The Many Roles of Bones

Beyond structure and support, bones serve various functions:

• Element storage (e.g., phosphorus and calcium)
• Blood cell production
• Sound processing (e.g., in ears)
• pH regulation and more

Diverse Bones, Unique Functions

Understanding bone variety and flexibility:

• Dogs vary from toy breeds to Great Danes with different skull bone structures.
• Dog shoulder blades allow greater motion due to looser connections.

Bone Fractures: Causes and Risks

Factors contributing to bone fractures:

• Severe trauma (e.g., accidents, falls, or fights)
• Common fractures in legs
• Even minor incidents can cause fractures, especially in small breed dogs.

Diagnosing Fractures

How to identify and confirm fractures:

• X-rays at a vet's office are essential for diagnosis.
• If you suspect a fracture, seek professional evaluation promptly.

Symptoms of Fractures

Recognizing fracture signs:

• Pain and lameness (especially in long bones)
• Swelling and deformity
• Hidden signs may also be present.

Handling Suspected Fractures

Providing care and transport:

• Assess vital signs and look for other injuries or shock.
• Transport to a vet as soon as possible.
• For open fractures, clean and cover wounds before transport.

Ensure your pet's well-being during transport, using appropriate support structures and materials.
