Once they get acclimated to water, Cocker Spaniels become great swimmers. Their love for water often makes for a great trip to a beach. However, the key here is to not force them into anything they are not willing to do. If you let them explore their ability to swim through positive reinforcements, they would turn into great swimmers. On the other hand, forcing them to swim would make them grow increasingly anxious of swimming and other related activities. Let them be on their own and Cocker Spaniels would make great swimming buddies!
