I'm new to the board and I've been reading all I can about sibling canine rivalry.
We have a four year old Westie (Hannah). She's pretty obedient and recognizes my husband as the alpha dog. We got an 8 week old lab mix (Harry) from the animal shelter this weekend and, as a result, have totally upset the balance of power at our house.
Hannah, the Westie, is a very friendly and outgoing dog. She likes meeting other dogs in neutral territory (like at the pet store or on walks). She really likes playing with Harry outside in the yard. There is lots of playful pouncing, chasing, and tail-wagging, but inside is a different story.
For example, Harry wanted to come upstairs and when he got to the top stair, Hannah growled at him. He went up anyway and Hannah pounced on him, snarling and barking. We broke up the fight because we were concerned with Harry's safety. Hannah didn't bite him, but she scared Harry as he went flying down the stairs, howling. We make sure to feed Hannah first, and she lets him know when he isn't welcome.
I have a few questions. Everything I'm reading tells me to support the dominant dog's position. Do you think this is going to get easier with time? Will they eventually get along? Are we supposed to encourage Hannah's dominance by petting her first, letting her take away toys from him, etc?
I want to make this transition easy on both dogs, so any tips and/or advice is very welcome!
