I have a 2 year dachshund who’s always been loyal to me, never goes to sleep until i go and favors me over my wife. I recently deployed for 9 months and came back yesterday and he has done nothing but growl at me and bark at me if i pet him. As soon as I walk away he cries and wants my attention and follows me everywhere its just when i pet him he gets mad. Could it be he’s mad at me for being gone for 9 months ??
