    • my mom's dog acted the same way when i brought home my new puppy. she went from acting scared to very aggressive though. my mother had to pretend that my dog didnt exist for a few days, act like her female was the only dog in the house. we kept them separated a lot. my dog was a puppy and didnt really mind or notice. We finally had to start feeding them different treats and dog food. Then they knew what was their's and what was the other dog's.The vet told us later that dogs can be very possessive.
