Opinions on spray bottle training?

Well, Its better to reward her when shes good then to punish her when shes bad.. I don't believe in hurting or scaring a dog to help train her. The best thing to do would be to keep her and the cat apart till shes used to cats ( to a puppy, a cat is just a strange thing!!) Also she should have a leash on at any time there is a door open or shes outside. Also, to prevent her from chewing on furniture, buy her rope chew toys and bones.
