As Walt said, its hard to evaluate without more observation. but in my experience, ur having typical signs of play biting, which is kind of normal for a dog her age, especially if she has been separated from her mom and siblings at a very young age. because mommy dog usually corrects that behavior when they do it to her, and playing with siblings her own age, would mean they are having the same behavior and they are rough play biting with each other, which makes them realize "heyy, thats annoying and it hurts sometimes" and they stop doing it how long have you had her for? and when did these behaviors start? where was she before you got her? how much exercise does she get daily? these are all factors to how you can move forward

i told them i would like to discuss additional charges in our meet and greet. thank you for letting me know i can adjust charges before booking. i just checked that out. exactly, i usually dont mind a few extra hours, but exactly 6hours is an entire day. and i didnt know how to address it. thankyou

thank you, sounds good. i mentioned it in my meet and greet reply. and i will mention it when we do meet. ofcourse i wont surprise the client with it last second. but honestly i didnt know if it was appropriate to charge more or not. so thank you for clearing that up

drop-off is at 11a.m. and pick-up is at 5:30p.m. the next day.
