Really depends on how allergic he is, if he can spend a whole day around a dog then he is probably mild to moderate allergic rather than severe.
So its probably manageable for him to stay with you but might want to look up a local hotel or BnB just in case after his first night he is in a bad way.
Designate a dog-free bedroom for him to sleep in. Start before he arrives by a few weeks. Wash all the bedding including mattress pad, put hypoallergenic pillow protectors on the bed pillows and then clean cases ovee them. Wipe down all the hard surfaces of the room with damp cloth, don't forget vent covers and window blinds. Then keep the dog out of this room the entire visit.
If you have forced air heat/AC, change the filter before his arrival.
Dust and vaccum and few days before his visit but don't use a regular vaccum during his visit as they will stir up dander and dust and get it into the air which is worse then just being on the floor.
Have the dog professionally groomed and fur blown out in the week before his visit.
If he is also allergic to environmental stuff like pollen, starting his antihistamines before the visit may be a good idea to knock back his body's overreaction to lower impact of the dog allergy.
He should also ask his doctor about using Nasal Crom starting a week or two prior to visit and throughout his stay (or just read up on it himself and try it, its over the counter and very safe) as it stops histamine reactions in the nasal passages before they occur rather than trying to fight them after basically
