There is a sweet lab that needs help. He owners can't care for her anymore. She is seven. She has lived with her same family her whole life. She also lives with cats and children and is good with both. I feel a connection to the dog but is getting her fair to my cats? I don't want them to be upset or uncomfortable. Also, I know the dog will be sad to leave her family....how long will it take her to adjust? Any thoughts are appreciated.
