This is the most incredible and most loved toy my two rat terriers have had over the last five years. My four-year old rat terrier, Palmer, wants to play with this little ball from the time she gets up and brings it with her to bed. The small loops fit in her tiny mouth easily. She loves to shake it, play tug of war with it and squeak it to draw attention to her human playmates. When she chews the loops off at the base, I have sewn them back on and away she plays again. She has two "loopy balls" (our name for this favorite) with many revived loops. I finally gave her the last new one I have saved. I really am in the market for a few more as I cannot locate them in nearby stores. Another great feature of this denim toy is that they are washable--yes, Palmer's gets covered with slobber.
