Well you can leave the dogs if there is local hotel- you could just come home to walk and feed them.
When it happened to us we filled jugs. Water in toilets was about 2 gallons if I remember and it worked for 2 flushes.
Not having water was worse than no electricity for me. The first day was the worst. Bet of luck to you! Hope it isn't a terribly expensive fix (ours was!!

- but we replaced pipe)
