My wisteria grows no whips

I brought a wisteria couple of years ago and my new puppy dog ( husky ) ripped it out and chewed it up, I thought it was dead, so I replanted it only 2 inches tall ( it was 10 feet ) so I went out and brought another one about 4 feet tall, forward 2 years on, my old wisteria is about 5 feet tall grows whips and very healthy but no flowers yet, the question I am asking my new wisteria is still same size, grows no whips so I car' t prune it, does have a lot of foliage, they are both in full sun, what do I do to generate growth, or do I have a plant from seed that might never flower.

Please let me know Barney.

  ps Ember the husky we still love you
