Dog is a lurcher, coming up for 9. He has never been a big drinker and until the last week or so has never got through a whole bowl of water in one day.
So he's not drinking excessive amounts but more than normal for him.
DH thinks it could just be because we've had a lot of dry weather and he's not finding his usual drinking puddles outside but I am worried it might be a sign that he's unwell (he doesn't seem it in any other way).
Any ideas?
