I bought this diaper wrap for my elder 15 year old border collie mix who suddenly hasn't been able to "hold it" through the night. The diaper wrap with a sanitary pad just could not hold the volume of urine my 27 lb. dog produced. By 6AM both the diaper wrap, the additional sanitary pad, along with the floor and the dog were thoroughly soaked with urine. I'd rather use a wee-wee pad on the floor and clean up the mess each morning than have my dogs fur soaking in her urine all night long and then have to bathe her, wash the diaper and wash the floor. Ugh! So very disappointed with the lack of absorbency, I threw it in the trash.
