i was reading the gwlittle catolog @ work last night. there is a little section about healthy living. it says using public water can be a danger for dogs. that their smaller systems are more susceptible to toxins. they say to use a drinkwell pet fountain system. i give romeo tap water in just a regular bowl. i'm not sure if he needs a fountain type system. if you want to take a peek it's at gwlittle.com item 413116. i'm sorry i don't know how to post a direct link. my fiance' thinks we should just give him water filtered through our brita system. i'm unsure.
