help my 4 year old samoyed won,t sleep in his kennel for love nor money .he sleeps on the roof of it .im terrified he,ll get sick.he used to sleep around the side of our house but grumpy aul bag next door kept letting him out on us so we had to move him to a new kennel in the back garden.he will go into it if we tell him too but just gets straight back onto the roof as soon as our back is turned.its been 6 weeks now. we also have been leaving our shed open for him but he preferes to sleep on the roof ,even in downpour
