Petmate Big Blue 5-Gallon Outdoor Water Bowl for Dogs & Cats – Durable, Made in USA – Ideal for Backyards, Farms, and Outdoor Adventures

More impressed than expected, very sturdy plastic and I like that where the water sits has corners rather than sloped to the edge (which I believe discourages my 9 months old pyrador from digging the water out) and having a 5 gallon jug on it really makes the whole thing solid and not easily tipped. I had a problem with my puppy digging the water out of the smaller ones and then tipping them over and proceeding to turn them into chewed up plastic.I opted to keep the original cap on my jugs to allow less water to come out when putting the jugs on. I cut 4 slits in the opening which worked perfectly for using my kitchen sprayer to fill and it is perfectly sized that way so it'll hold the sprayer on and fill without me holding it. I have had them two weeks now and have only had to fill them once a week with 3 dogs (small, medium, and large) and they are still about 1/4 full when I do (to prevent it from becoming light enough to play with). I have them in a metal tray intended for a kennel that I had for containing any splashes (which may be temporary as I have a feeling it may rust down the road)I intended to use these temporary since they weren't expensive until I found a more durable design but the design has seemed to make them less fun to play in and with by my puppy but great design for me since I don't have to clean up water off the floor anymore.
