Grooming and coat
Why do my clippers overheat or pull my dog's coat?
Last updated 23 September 2026 · How we write and check this
Short answer
Clippers overheat and start pulling hair, rather than cutting it cleanly, when the blade is dull, dirty with trapped hair, or lacks oil, or when the coat is too thick or matted for the blade being used. Stopping every few minutes to oil and clear the blade usually solves the problem during a longer session.
The most common cause
A blade running without enough oil generates friction between its moving teeth, which heats it up within a few minutes of continuous use and dulls the cutting edge faster, at which point it begins to grab and pull hair instead of slicing through it cleanly, something a dog notices immediately.
Coat density can overwhelm the wrong blade
A blade suited to a short, single coat will bog down and overheat quickly on a thick double coat or a heavily matted area, since it is being asked to cut far more hair per pass than it was designed for. Brushing out as much loose hair as possible before clipping reduces the load on the blade.
A routine that prevents most issues
Oiling the blade before starting, wiping away trapped hair every few minutes, and letting a clipper rest for a minute if it feels warm to the touch keeps a session running smoothly. A blade that still pulls after these steps likely needs sharpening or replacing rather than more troubleshooting.
Key takeaways
- Insufficient oil is the most common reason a clipper blade heats up and starts pulling hair.
- A blade can be overwhelmed by a coat that is thicker or more matted than it is designed to handle.
- Regular oiling and clearing trapped hair during a session prevents most overheating and pulling issues.
