I agree three weeks was the magic number here as well.We lost our old girl in jan,at 13 yrs...,,,she had grown up for ten years with my other dog...talk about symbionts...they walked in brace, shared treats,loved each other to bits. Then she died with a brain stroke...literally from one day to the next...gone.......The second dog was so lost,didn't eat,mourned her best friend.
So what did we do...we brought in a new pup,same breed....but a bouncing male. yeuwwww.If a dog could snort disdain ,my girl did.Worse still he arrived at night after a long flight from Sweden and was put on our bed as the old pair had been...whaaaat.?Her world turned upside down overnight...we had a week of snarls, a week of denials and a week of warming up.Now after three months she accepts him,but still refuses his invites to play and his toys that he brings to her.
I don't expect them to be best friends,but I'm happy that my old darling now accepts him...that's all I ask of her.She no longer leaves the room at his arrival,will share my double bed with him and travels nicely in a car next to him.She is a good soul...so is he...it will all work out as will your new arrival.My best advice is have patience and don't expect too much too soon.Plus each new pairing is different ....nothing can ever be the same .
