I have a stupid question

do Boston Terriers have dander all year round or is it just a spring thing?? The reason I am asking is that my husband's allergies to Jay doesn't seem to be letting up

?? We changed Jay's food to Royal Canine ,I give him a brushing every day out side and I take a swiffer cloth to him befor I bring him in, I also bath him with deshedding shampoo and deshedding solution once a week. I seem to be

my head against a wall, any other suggestions?? Or should I use HEAD & SHOULDER'S to get rid of the dander?? Need reply soon thanks
