we had to brush our collies [one was a whippet cross and he wasn’t as bad] every other day and hoover every day. Diet didn’t change a thing and washing them… well we only did it every now and again at home otherwise the bathroom looked a mess. I think most collies have this issue though.
Wish I could shave my white cat though… tried hoovering it the other day while it was sleeping got the hose near it and it climbed up the curtain in flash… had a row for that.
