Not sure whether this is in the right section! Feel free to move me!
During the night - usually around 3am Dexter pulls his fur off his legs, the feathering part and chews it

the noise of him pulling it off usually wakes me up so I then have to try and prize the fur out of his mouth but usually he manages to swallow it before I get chance.
He has always done this to some extent but now he is getting big boy feathering it seems worse!
Is there anything I can do to deter him. I don't want him becoming poorly from swallowing fur!

Does anybody elses cocker do this?
