Clean your dryer's lint screen after every load — pet hair or not — by removing it, wiping or lightly brushing off the buildup, and checking your manual before using water. Both LG and Whirlpool document this as standard maintenance, and pet hair simply makes that lint buildup more visible, not more frequent to clean.
What LG and Whirlpool Actually Recommend
LG's dryer maintenance guidance instructs owners to clean the lint screen after every load, since lint and fiber buildup restricts airflow and reduces drying efficiency over time (source). Whirlpool's owner's manual gives the same after-every-load instruction for its lint screen and includes model-specific steps for removing and reinserting it correctly (source). Neither source says pet-owning households need to clean the screen more often than that — after every load is already the standard, maximum-frequency guidance for all users.
The Safe Cleaning Steps
Pull the lint screen out according to your model's release mechanism — never force it. Remove loose lint and hair by hand or with a soft brush, working in the direction of the mesh rather than scrubbing across it. Pet hair tends to mat into a felt-like layer on the screen; peeling it off in one piece is usually easier than brushing it loose fiber by fiber.
When Water Is (and Isn't) Appropriate
Some lint screens are rated for occasional washing with warm water and a soft brush to clear embedded residue, while others aren't designed to get wet at all. This varies by model, so check your exact manual before running your screen under a tap. If your manual allows washing, let the screen dry completely before reinserting it — a damp screen restricts airflow just like a clogged one.
What Not To Do
Never run the dryer with the lint screen missing, damaged, or visibly blocked — both manufacturers treat an intact, clear screen as a baseline safety requirement, since blocked airflow is a recognized fire risk in clothes dryers. Don't attempt to disassemble the dryer cabinet, duct, or internal housing to chase hair further into the machine. If lint or hair is building up inside the vent, duct, or drum area beyond what the screen itself catches, that's a job for a qualified appliance technician, not a DIY fix.
Reduce Hair Before It Reaches the Dryer
Less hair on fabric going into the dryer means less work at the lint screen. A portable pet hair remover glove used during regular grooming cuts down shedding onto clothes and bedding, and a reusable pet hair remover roller can pull loose fur off items before they're washed and dried.
Bottom Line
Clean the lint screen every load, follow your exact manual on washing it, and never run the dryer with a compromised screen. For anything beyond the screen itself, bring in a technician.
Frequently Asked Questions
How often should I clean pet hair off the dryer lint screen?
After every load — that's the standard guidance from both LG and Whirlpool for all users, not a pet-specific increase in frequency.
Can I wash the lint screen with water?
Some models allow it; others don't. Check your exact owner's manual, since this varies by model, and let the screen dry fully before reinserting it.
Is it safe to run the dryer if the lint screen is damaged or missing?
No. Both manufacturers treat an intact, unblocked lint screen as essential, since restricted airflow is a recognized fire risk in dryers.
What if hair keeps building up beyond the lint screen?
Don't disassemble the dryer yourself. Buildup in the vent, duct, or internal housing should be handled by a qualified appliance technician.
