Book Recommendations on Introducing a New Puppy to a Home with a 2 yo Dog

Hi All,

My husband and I currently have an almost 2 year old black male Labrador. In a little over a month, we are welcoming in an 8 week old female yellow Lab. We are so excited and know Boomer will be overjoyed to have a sister. I want to make this transition as easy as possible for all 4 of us.. Are there any books, reading materials, YouTube videos, etc. that you would recommend? I have seen many recommend their initial meeting be outside and to have shorter interactions the first few days to let them both acclimatize to eachother. Any other tips? I have never owned 2 dogs at once so any advice is appreciated!
