We gave this ceramic pet fountain to our yorkie. We loved the quality feel of the product. The set up of the pet fountain was easy and quick. We did make the mistake of plugging in the product without first adding the water, the sound scared our yorkie. After adding the water the sound went away and it was quiet. My dog is still afraid of the fountain but we are keeping the fountain close to her bowl area's to get her used to drinking from the fountain. I would highly suggest and recommend add water before plugging in the product as to not frighten some skittish pets.
