Dear Buddha Amithabbha,
May whatever over exhaustion she has had in the last few days heal with lots of rest and barely any walks. I will also carry her up the stairs for a few days and into the car instead of having her exert any effort on her joints. Unless she shows no hesitation.
I did not know such young puppies are quite limited in their walking possibility and safety to go hiking. Ignorance. Now we know.
Please Buddhas, let her rest and heal quickly in case any soreness or anything was overexerted and become strong and healthy as a youn teenager pup in a few months.
