Dogs and cats are 2 different species so I doubt you'll have any success training the dog to leave small dogs alone from training with a cat.
Huskies are notoriously high prey driven and usually do not do well with small animals. Most I've dealt with were fine with all other dogs though regardless of their size.
If you don't have the training into this dog that it will listen to you under ALL circumstances, I would advise not bringing her to an off leash park unless it's separated by sizes.
There are many with a smaller dog area and a larger dog area.
Knowing what you know about her, it would be very irresponsible to bring her and risk the safety of any small dogs that go there as they have every right to be there safely.
