Question
we have 3 dogs 2 english cockers and a jack/pug cross(6 months) when we go to the beach she howls and barks and whines setting the other dogs off, when at the beach, we leave her in the cage before letting her out and turn our backs on her, but she is mental when she is let out, she is seting the others off , i know she is excited, she gets 1 90 min blast and 1 20 min walk a day.

Thankyou

Answer
This is a young dog anticipating having a grand time and she's being unfairly confined.  by the time you open that door, she is like a wound spring ready to pop.

Introduce play training to this dog, she's a perfect candidate.  Here's a link:

Once you have introduced it, take the play object with you to the beach and let this dog out of the car before the other two.  Redirect her enthusiasm to the play training object and ask her to 'work' for a few minutes.  As it will take some time to develop this skill (a couple of weeks), until then take her out of the car first.  Confining her and ignoring her when she is so wound up and excited is worsening the problem.
