hairballs

my son Merlin (1-1.5 year old standard poodle) looooves to chew. he has so many chewing toys and would probably chew all day if he could. we’ve got him in a Miami cut now, and I think while he chews his toys he’s been biting off/swallowing pieces of his hair accidentally. I didn’t realize the hair was getting swallowed until he threw up two big hairballs this week— I thought it was just clumps here and there that I pick up and throw out. does anyone else’s poodle do this, or is my boy just a lil freak? does anyone have recommendations for a cut that will be as cute as his Miami but not have bracelets? lol ugh
