What about a leash and (serious) harness? Something that would limit the distance and prevent the pup from actually getting close enough to take a leap(?) I'm not talking about a harness made from straps, but one that would cradle the chest and stomach area enough to gently suspend (him) in the air -- just in case.
Granted, you would have to take it on/off every time your dog goes onto the balcony, but it's the only thing I can think of to really make sure your dog is safe.
Thanks for all your help! As I mentioned previously, it was the trainer that
said there may be some basenji in this dog. We had never heard of basenjis,
so it's been interesting to learn more about them, whether or not she has any in her. Thanks again for your input!
Nala will sometimes sit at my feet while I am doing dishes…she is so warm and still that I sometimes forget and -- DUH! almost trip and fall over. She has almost taken out a few of our guests at times though...
