I would agree with Rod that a hearing test isn't essential unless you think your dog is going deaf. Oliver had his first BAER 2 years ago, when he was clearly having problems in one ear. His second test last May was to see how things were going, and his deafness in both ears has increased. This is useful information, as I now know that he won't hear me calling his name when he is off-lead, but he can still hear clapping to get his attention and then I am using more hand signals to call him in. But if your dog isn't showing any signs of deafness (Oliver's first sign was if he was lying on his good ear in bed, he wouldn't hear me coming into the room), there isn't much point in having a BAER (especially if you have to pay for it!).
