Regarding not playing tug because of teething, is this just when adult teeth are coming in at 5 to 6 months? Or sooner? I play gentle tug with Asha and only at her head level, let her do the pulling. Seems I read somewhere not to let puppies tug hard or not at all until they have their adult teeth? She'll be 15 weeks on Sunday. This is strictly regarding her future in IGP and not wanting her to have any pain associations with biting or the tug.
