ok, so my 8 year old terrier has always had a thirst (he drinks far more than the other 3)....but tonight he was lying down on the living room floor and wet himself 
Then about an hour later he weed again in the kitchen. Now i am going to book an appointment with the vet tomorrow first thing....but does anyone have any ideas on what it could be ?
Now the funny thing is, the other 3 were all avoiding this puddle like the plague, and not through guilt (ie: me thinking it was one of them lol ) ...but then one of the girls sniffed it, walked past it and then weed on the floor too !!!
The reason this is funny is because she has never ever toileted in the house, she is very, very clean....
So i am wondering if there is something in this wee (ie a smell) that has freaked them out a bit ?
I've had a google and can see there are all sorts out there, diabetes, cushings etc but wondered if anyone else has had experience of this ?
thanks
