Get a good vacuum cleaner and get used to using it alot.
There are some nutrition supplements that claim to help.
We have an Akita and she blows her coat twice a year for about 2 mos each time. She does not have free reign of the house so that keeps the hair contained to a certain extent. She generally stays in the family room on her huge dog bed or in my son’s room which has laminate flooring. I am just used to vacuuming 2 times a day in those areas. I did buy a cheap bagged vacuum that works great...a Hoover widepath tempo. I think it was around $80 but works better than my much more expensive vacuums. Oh and I trained her to only shake when she is outside LOL!!
