Can you purchase Flea treatments that you give to dogs orally as my Lab named Bailey is always in water and the type you put under his fur just wash off in the water. Maybe the fact that he swims virtually every day will alleviate the need for treatment.
Bravecto and Nexgard are oral treatments effective against fleas and ticks. They don't prevent the dogs getting bitten, but they kill any flea or tick that does bite.
