We have had Lily for 9 Years and she is one of the most well behaved dogs I've ever seen (well, except during rain storms and fireworks, which is another story.) When we brought Izzie home, Lily was so excited to meet her and was very loving and affectionate (like a proud sister.) Until the next day... when the puppy wanted to play, Lily ignored her and any time the puppy went to cuddle next to her, she walked away.
I don't know if Lily got irritated with the puppy when she was up barking all night (probably the first time she was in a crate by herself over night) or she got jealous of the puppy... but I'm looking for some feed back here.
Is this normal behavior? Have you had an adult dog ignore puppies? Do you think they will get along better when the puppy grows up a bit? Lily isn't aggressive towards Izzie at all and even lets it go when Izzie is chewing on her favorite (and only) toy. Lily was never really big into "play" (she never liked toys, all she does is chase light and when she was littler she would chase us in the yard) and is just content cuddling up to you. I'm guessing their personalities are just different, I just expected from Lily's initial behavior that the two were going to get along great!
Lily always looked lonely and I thought getting her a friend would be a wonderful way for her to cheer up a bit, but maybe she's too old now for a puppy. :-/
