my 7 month old pup has wart like things on top of her head, there is a really big one and lots of little ones, she lives with other animals and im trying to decide whether to take her to the vets, so they can be treated so they dont get past onto the others.  they dont seem to be bothering her, but she did rub her head on  the carpet quite alot the day before i noticed them. 
any ideas would really help
thank you

Hi Guest - what breed is she?

Are they ticks?

I was thinking the same thing digger
