We're welcoming our second dog home this weekend. She's a lovely, gentle 2 year old show cocker. Ddog is a soppy 7 year old show cocker, and although is an only dog, is used to sharing his space and family (as we often dog-sit my sister's dog).
In terms of introducing new ddog, I know to do this on neutral ground. I've sorted out new bed, a baby gate for the kitchen (to give new ddog her own space while she settles in), and separate feeding areas for the time being. (Both are neutered/spayed, and neither are bossy/dominant - similar temperaments.)
What else do I need to consider to make it a smooth transition for both of them?
