Border Terrier Q&A
Border Terriers can be teached to swim and they will enjoy it but be carefull that there is always someone with the dog when it is swimming and also I would wait until the dog is 9 months before I let in the water so I know that it is strong enought to swim.
My dog definately does! He was timid at first, but now he's learned to swim freely without going in too far. And we even throw in tennis balls for him!
