HI from MICHIGAN !! and yes its cold !
we walk 2 xs a day - very qiuck ( 6 blocks or so ) them play in yard till ( i am cold ) Sam has a coat on also ! but we have a play date 2 days a week with my sis's pits ( sam sleeps for a good 24 hrs after ) THEY RUN HARD (in a fenced yard )and jump n play and this keeps him content this time of year - as its to cold for me to give him enough out side time. so maybe find ur guy a play date ... easier on u ! i promise and he will sleep the entire ride home - we do alternate homes ( so non of the dogs get to "posessive " (sp)of home ) she has a male & female - sam is a male ( all fixxed )
but he did get a little beat up today - even though he didnt seem to mind as much as poor mamma did !!

.... lots of porixzide n kiss's, he just looked at me like i was stupid !!
but sleeping like a baby in my lap !!!
let us know how it works out~~~ btw Sam is 2 yo
