I have a one and a half year old toy rat terrier that still goes potty in the house ive triad puppy pads litter boxes and of course spanking what else should I try?

Potty training a dog can be challenging, especially if traditional methods haven't worked. Instead of punishment, focus on positive reinforcement; reward your dog when it goes outside. Establish a consistent routine for bathroom breaks, taking them out after meals and naps. Additionally, consider consulting a professional trainer or veterinarian to rule out any underlying health issues that may be affecting their behavior.
