Abstract

A canine diaper assembly includes a band that is wearable around a canine's body. The band is constructed of a fluid impermeable material to inhibit urine of the canine from passing through the band. A first tab is coupled to and extends away from the band and a second tab is coupled to and extends away from the band. The second tab is matable to the first tab for retaining the band in a closed loop around the canine's body. An absorbent pad is integrated into the band to absorb urine from the canine. A reactive strip is integrated into the band and the reactive strip is comprised of a material which chemically reacts to urine. The reactive strip changes colors when the reactive strip is exposed to urine to visually communicate that the canine has urinated into the absorbent pad.
