We have a little westie/ cairn terrier cross. From the minute we brought her home, she has loved this toy... even when it was too big for her to carry (she still trips on it at 3.5 months) or shake, she would try. When she goes to her toy basket, this is almost always the first toy she brings out, and anyone who is on the phone with me at the time will attest to her enthusiasm. She is not a barker, but she will bark when I throw this for her! :)
