We bought this to keep water off our dog's beard hair. Dog is 7 pounds.. Three issues caused us to throw it away. First, we couldn't figure out how to stop those little drip drip drips. Over night all the water would come out. Also the screw cap had to be put on jusssst right or the water would gush out around the cap. The cause seems to be only 1 1/2 thread engagement between screw cap and bottle. As a result screw cap has to be put on carefully to make sure no under tightening or over tightening. Third, if the bottle wasn't mounted perfectly vertically then the water would drip out faster (this seems to the way with all of these type lickers not just Lixit). The fourth issue was the dog had to lick lick lick lick a lot to get enough water especially in hot weather. We ended up buying and a 1 quart round Lixit with a bigger pipe. If we mount if vertically then it only drips a few times before it stops. If you have a dog without a beard we suggest using a water bowl.
