Question about potty training. I often see advice from trainers to take the puppy to the same spot outside. But won't this teach them to go to only in that one spot? I understand that having a dedicated spot is very convenient, especially in bad weather when business needs to be done quickly.I'd like for the puppy to be able to potty outside in general, on walks, and not hold everything in until he gets the dedicated spot. Thank you in advance for your input.
