I live in my aunt's house, she has 2 dogs. before usually when i get home they would come to me but lately they dont, instead they bark at me. well they bark when i get home, they cant even see me but for some reason when i open and step inside the house they bark. the weather has gotten really cold lately, would that be why? i asked my aunt if they do the same to her she says no but i think thats because everytime she comes home from work shes got food for them, everytime. n i dont. what do you guys think this might be?
