I was taking Murph and Oz for an hour walk every night, until
Murph hurt his knee. He lives to go walking so he can pee
on every tree or bush or blade of grass we pass. He looked
so depressed if I took Oz without him. He'd press his lil' nose
against the window looking at us with a forlorn look. So I only
take Oz a couple of times a week now and then just play frisbee
with him the other days. Once Murph's knee is fixed, we'll go
back to once a day again.
