Ever noticed your dogโs coat ripple when a fly lands?
โ
That subtle twitch you can see on Tucker and Midge isnโt random.
โ
Itโs the ๐๐ฎ๐ญ๐๐ง๐๐จ๐ฎ๐ฌ ๐ญ๐ซ๐ฎ๐ง๐๐ข ๐ฆ๐ฎ๐ฌ๐๐ฅ๐. A thin sheet of muscle that sits just under the skin along the sides of the body.
โ
When the skin is stimulated, this muscle contracts reflexively. The result is a quick flick of the coat that helps dislodge flies and irritants without the dog even turning its head.
โ
No scratching.
No twisting.
Just efficient design.
โ
Clinically, this reflex is more than a fly swatter.
โ
We assess the cutaneous trunci response as part of a ๐ง๐๐ฎ๐ซ๐จ๐ฅ๐จ๐ ๐ข๐๐๐ฅ ๐๐ฑ๐๐ฆ๐ข๐ง๐๐ญ๐ข๐จ๐ง because it reflects sensory input and spinal cord function through the thoracolumbar region.
โ
So that little ripple along their sides?
โ
Itโs protection.
Itโs reflex.
Itโs healthy nerve communication.
โ
Nature doesnโt miss much.
