My lab is shedding a ton right now too. Labs always shed, but there are times of the year where they molt and it just keeps coming and coming. It happens a ton after they dry off from being wet. Unless you're seeing bald spots, I don't think there's anything wrong with your dog.
Your dog is 5. Has it always shed like this, or is this a new thing?
Welcome to having a Britt! If your dog will tolerate brushing a Furminator will take a ton of fur off. I just live with the fact there will be white fur on anything either of mine come in contact with.5 yr old Brittany sheds tons ,brushing , food change , Dyna -vite , worked on some other issues , but no help with shedding. Any suggestions ?
