I have two of those who moult ALL the time,no matter the season!!! But their hair fortunately is very short.I used to have one with long hair many years ago,and I had the same issue as you!She lived till she was 14,Bless Her !! These with the short hair,though plenty of it,I find easier as I can sweep a lot of their hair with a broom,as I now have mainly wooden floors.I have to do THAT sometimes TWICE a day though!! Nothing in the world would induce me to ever NOT have these beloved Fur Babies,as they truly are my world!
We don't have much space to use the medium size vacuum cleaner, but we do also have a handheld 1, that needs emptying after the 3rd or 4th use. As you would all know, they only last 20 mins before they have to go on recharge.
