What water is safe for my dog? Tap, filtered, or distilled water?

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 7 years and 6 months old | 17 lbs

What types of water are considered safe for dogs and which types of water are consisted potentially harmful, and should be avoided? I’ve heard to avoid reverse osmosis, alkaline and distilled water. It seems the general consensus is that these types of waters can strip the minerals out of the water, which is not good for the dog. I’ve been giving filtered water to my dog, Is this safe to give and will it strip the minerals from the water? Also, is tap water and bottled or spring water safe also?

Any water that is safe for humans to drink is safe for dogs. If you are feeding a normal, commercial diet dog food that is AAFCO certified, it is fortified to contain all the needed vitamins and minerals so the content in the water isn't really a concern. The vast majority of dogs drink tap water and do fine (as long as it is safe to drink). I hope this helps.
