[Mas]

My 18 months female Jack Russel keeps weeing in the house- any where.. on the bed, floor, chair.
She knows its wrong.. she is a very happy energetic dog and I have had her from a pup... she knows outside is where she should go to wee.
She has also started to chew furniture, im at my tether, just dont know what to do anymore, I have started over and over to go back to training, but she keeps going back to being dirty.
Can anyone help ??
