A raincoat that has been through a muddy autumn, a pair of winter boots and a knit sweater for a small dog all end up in the same state: damp, smelly and quietly losing the properties you paid for. Pet apparel needs a different routine from either human laundry or hard gear, and getting it right is mostly about temperature, detergent and drying.

Why Apparel Needs Its Own Routine
Two things wear out pet clothing faster than dirt. Harsh detergent and high heat strip the water-repellent coating from a raincoat and flatten the loft in an insulated jacket. Fabric softener does the same damage while leaving a residue that traps odor. On top of that, apparel worn against the skin picks up dander and oils, so a garment that smells clean can still irritate a dog with sensitive skin. Cold water, gentle agitation and a mild detergent cover most of it.
Before the Wash: Debris and Fasteners
Mud goes down the drain and clogs your machine, so shake and brush off what you can outdoors first. Close every zipper, buckle and hook-and-loop strap, and loosen the cinch cords. This stops hardware from snagging fabric or banging against the drum, and it protects straps from being stretched out of shape. For a raincoat, use a mesh wash bag, because buckles are the single most common cause of torn fabric and scratched machines.
Fabric by Fabric
| Item | Wash | Dry | Never |
|---|---|---|---|
| Waterproof raincoat | Cold, gentle, technical fabric detergent, in a wash bag | Low tumble for 15 minutes, or hang | Standard detergent, hot water, softener |
| Fleece or insulated jacket | Cold, gentle, mild detergent | Air dry or low heat | Fabric softener, high heat |
| Knit sweater | Cold, gentle, extra rinse | Lay flat to dry | Hangers, which stretch the neckline |
| Rubber or fabric boots | Cold, gentle, or hand wash with mild soap | Air dry away from radiators | Direct sun and high heat, which warp soles |
De-hair knits and fleece before they go into the machine. A damp rubber glove or a rubber-bristled brush lifts embedded fur far better than picking at it by hand. Run an extra rinse on anything that touches bare skin, because detergent residue is a common cause of itching under a coat.
Drying and Restoring Water Repellency
Air dry everything that has buckles, straps or a rubber sole, hanging it away from direct sun. Technical fabrics can go in the dryer on low for about fifteen minutes, because the gentle heat re-activates the durable water repellent finish. This is a genuine trick rather than a myth. If a raincoat has started soaking through at the shoulders, it is time to re-proof it with a product made for outdoor fabrics, following that product’s own instructions, and to reapply once a season if the garment is washed often.
Storing Between Seasons
Wash and dry everything before it goes into storage. Keep items in breathable cotton bags or a ventilated bin, sorted by season and labelled if you have more than one dog. Avoid sealed plastic, which traps any remaining moisture and turns into mildew by the next cold snap. Fold knits rather than hanging them, and do not compress insulated jackets into a tight stack, because the loft is what keeps them warm.
An hour of care at the end of a wet season gets you apparel that still repels water, still insulates, and does not announce itself to the room the moment your dog walks in.
