We have had Kimber for two weeks and Kelsey still seems to be irritable with her. She doesn't like play with Kimber and is still territorial. I don't usually mind but a few minutes ago Kimber was playing with a ball the rolled over to where Kelsey was sleeping and when Kimber went to get it Kelsey gave her Kujo growl. Kelsey mostly ignores Kimber but Kimber wants to play and she won't which I understand but I don't want her being so territorial and grouchy. What if anything should I do?
