I am currently owned by a two year old pembroke corgi. My husband and I are thinking about rescuing an adult corgi. I'm curious about others experiences with introducing a new dog (particularly adults) to an adult corgi's home. I'm terrified that they might not get along and the new dog will have to be returned (this would absolutley break my heart). My corgi is by no means aggressive towards other dogs, but she will growl a bit sometimes. Does the dog's gender play any difference in your experience? Is there a difference between introducing puppies and adult dogs? Thanks for your help!
