I have had many different breeds of dogs. Fixed and not fixed. I have always taken them to the beach...sometimes they listen perfectly and other times they take off like a bandit! What I came up with is...to put the dog on a really long nylong thin leash and leave it on at all times. The dog does not really notice it is there and it is always handy to grab quickly if the dog decides to take off...or if you find yourself chasing the dog(haha) it is easy to step on... Treats, whistle, etc all work, but the dog- will at sometime-take off....and it is always good to be prepared... LOVE THE BEACH ALWAYS! A MUST FOR DOGS AND OWNERS!
GOOD LUCK
