I've had her for about 2 months and I've basically let her pull me when we walk. I've briefly tried many times leash training her by stopping and turning around whenever she'd start pulling but I gave up in the past after 5 to 10 minutes of failure. I would really like to leash train her, but it's more for my own selfishness just because it can get annoying when she pulls on me. I kind of feel like it would be unfair to her to come up with new rules after 2 months of allowing her to pull and she'll get frustrated and I should have either done the training from the beginning or should not at all. What are your thoughts?
