A male libra dog (1994) and a male leo rabbit (1987).

Hi Toby, this could have to do with the fact that you are talking about a FIRE rabbit, fire rabbits are more bold than other rabbits, they have the fires of passion burning inside of them, and usually don't shirk any opportunity that comes their way to get what they want, so yes a fire rabbit will chase a dog, however the dogs instincts should kick in eventually, especially if the rabbit is sitting on the fence, dogs enjoy the chase too and will naturally go into chase mode if their desired partner may be playing hard to get, but with this combination one of u will wind up chasing the other eventually until you catch each other, can be a fun game;), but be warned male rabbits too tend to shy away from commitment, at least at first they do;)
