A Dog Found Today!

I hope someone can help! Today we found a little dog here in Rojales/Formentera near the British indoor market, all wet, dirty and scared, We took her in, fed and dried off, I am not sure its a girl or boy, looks like girl, all white with brown patches round her eyes and ears. The dog has a stripy collar pink with white. She is less nervous now warming up, I will take her to vets today,fingers crossed, there is a micro chip, if not, if anybody knows anybody looking for their doggy, small hairy breed, please get in touch and I will send the pictures. i hope she does belong to somebody and will be found! if there is anywhere else i can put the notice up please let me know, this is the first time this has happened to us and we are not sure where else to notify! Thank you.
