Unless the water is coming from a well and may have substances or bacteria in it which can generate a reaction, I would say that normal treated and clean water should not result in any allergies. However during a long phone consultation that I had with Dr Beltrand (Blair's animal hospital, which is both traditional and homeopathic medicine), he told me that the chlorine in the treated water actually exacerbates inflammation. That means if you have a dog who has arthritis, or if he has an ailment which later turns into arthritis (e.g. my dog has elbow dysplasia), then he told me that investing in a GOOD water purifier that actually gets rid of substances like chlorine is a worth while investment (for the dog and the family). Of course really good water filters can be expensive... so for now I admit we have held off, but ideally the purer the water and the less substances like chlorine in particular, the better, for them and for us. Hope this helps!
