The splenius is more than just a neck muscle; it supports feeding, carrying, chewing, listening, and overall stability. It works quietly in the background, but without it, many of a dog’s daily activities would be harder, less efficient, or more tiring
We'll be breaking down some of the individual and main muscle groups in our muscular info series for pet owners.
For those who want a bit more detail then keep an eye out for our Professional Series with more anatomical detail later in the month of October!

Splenius in the Dog – Functional Role
The splenius muscle lies along the upper neck and is part of the epaxial muscle group. Beyond simply extending or rotating the head and neck, it has direct links to everyday functions that matter to dogs and their guardians.
1. Feeding
When a dog lowers their head to eat or drink, the splenius helps them raise their head back up.
During chewing and tearing, the splenius stabilises the head and neck, allowing the jaw muscles to work more efficiently.
2. Ball Carrying or Holding Objects
Dogs often carry balls, toys, or sticks with pride. The splenius helps maintain an extended neck posture, resisting gravity so they can comfortably hold objects in their mouth.
This muscle provides the endurance support needed to keep their head lifted while carrying.
3. Jaw Function
Although the splenius does not directly move the jaw, it provides a stable base for powerful jaw muscles like the temporalis and masseter.
This stability allows dogs to bite, chew, and tug without their head being pulled off balance.
4. Ear Function
The splenius does not move the ears directly, but by turning or tilting the head, it helps dogs orient their ears toward sound.
For example, when a dog pricks their ears to listen, subtle neck adjustments supported by the splenius make this possible.
