I've unpacked the grehound's winter coats and despite washing them before they went away for the warmer weather, they are still covered in his hair. So much for the non shedding dog I was promised 🙄. What am I missing for cleaning them? I've put them (dry) in the dryer with a bouncy ball, gone over them with rubber gloves, left them on the line in a storm. Next step is giving him a blade 1 and removing the problem at the source.
