@j2122jessie: This is our dog water fountain that we use and love. We have four beautiful fur babies and we usually only have to fill it about two times a day. It has two filter systems in it it is motion sensors or you can have it on time. We wash ours every time we fill it back up and you can pre charge and not have it plugged in the whole time if you are afraid of them getting electricuted. Overall it’s big and works dress for 4 dogs size medium to large. Also we got this Matt that helps with any water that may splash off cuz we have messy drinkers around here. Only down fall is it collect dog hair a lot so it has to get clean a lot. Over all we love ours if you want one link below.
