A pet bootie is formed by a sleeve of pliable, disposable and liquid impervious material having a closed end for receiving an animal's paw and an open end. A loop of elastic material has an inner end secured to the sleeve at a predetermined distance from the open end of the sleeve and projecting outwardly from the sleeve. The loop is of predetermined extended length for allowing the loop to be extended around the sleeve and the animal's leg when the paw is inserted into the closed end of the sleeve, whereby the sleeve is secured in position.
