"Rosie" seems to be a quick learner... she sometimes uses a noise device (not quite a bell) on the door to go out... definitely uses it to go in. Rosie and Blue (our female Kerry Blue Terrier) seem to have formed a bond quite quickly... they play together like puppies... lots of tug of war and chase. Unique in my experience in bringing terriers together with a 5 years age difference...
Here is Rosie...at 9weeks... (promise I won't keep sending puppy photos)
