We've had chemical castration for our dog the last year, the past weeks now it's been going out of his system, so he's super intense all the time now, no rest, no sleep during daytime etc. So until we get it permanently fixed - I'm working on solutions. So tonight I walked the neighborhood 5-6 times while he drags a car tire (I made that last year for him), I just stroll along while he drags and work until he's done, so tonight at least I have a sleepy restfull dog here :) Nice! Easy fix that does not make me tired.
