Check the complete care label, seams and backing. Pet bedding can contain heavy hair, padding or materials that need different treatment from ordinary clothing.
Understanding this situation
An item that washed successfully may still prohibit tumble drying or exceed the dryer's bulky-item limit. A damaged backing can shed fragments that should not be treated as harmless loose hair.
A useful next step
Use the specified drying method and appropriate load quantity. If debris or an unusual smell appears, stop further use and report the bedding construction. Do not raise heat to remove odour or dry an unsuitable filling more quickly.
