Your Bravehound sweater can be washed easily in the washing machine. You can use Fast/Quick/Speed cycle recommended temperature 30-40 degrees cold-warm setting (NOT HOT). The important thing is to use a mesh laundry bag that should not be much bigger than your sweater. Using this bag will help cut down the amount of friction the sweater is exposed to.
Fortunately the wool sweater does not shed, so you can put it in the washing machine with other laundry. Lay the sweater flat and let it air dry (do not use a machine dryer). You can speed up drying by placing the sweater near an open window, fan or dehumidifier.
If you notice the sweater stretching out too much )as is normal for all knitwear), you can put it in the washing machine to "jump" back to it's original size and look brand new.
