My mom’s elderly dog passed away from kidney disease brought on by chronic dehydration. Because this worried me so much about my aging dogs, I’ve made it a point to always have fresh water available for them. This dog water fountain is so cool! I’m not very technologically-saavy or handy, and the directions were super easy to follow. The unit is very quiet and we have barely noticed it being on besides a very low hum. My dogs have not yet taken to using it yet, and we may have to train them a bit to approach it because they are the types to be afraid of their own shadow! We are bringing home a new puppy this fall, and I plan to train her to use the fountain from the very start. Highly recommend, especially in hot weather climates like ours!
