Border collie is my friends by the way

Answer 1

Very cute puppy! Im not sure how to help you though!

Answer 2

Spray her with a squirt bottle filled with water every time she barks

Answer 3

A good way to help curb a barking dog is to train it to bark and stop barking on command. So if your dog barks on its own usually commanding it to stop is easier. Also some dogs just have issues with other dogs, you might need to train it to focus on you when you see another dog coming try giving her treats and telling her to focus on you. and repeat until eventually she learns that focusing on you when other dogs are near by is the way to go. If not a treat maybe you can find a special toy she only gets when other dogs are around, but that might be a little harder at a beach with other dogs.
