Why does she do this?

[Giselle]

How old is she again? I wouldn't expect a young puppy to have perfect walking skills. The criss crossing and bumping into you just sounds like puppy boredom kicking in. Young pups don't really tolerate long walks well because they get bored easily.

Thanks. She's only 14 weeks old. I just wanted to make sure I wasn't missing something subtle. She's really been walking very nicely on the leash so we'll just keep working with her

Oh yeah, she's definitely a young'un. I wouldn't push her for nice loose-leash walking skills until she's about 16 weeks. At that point, you can start being stricter because her attention span is longer
