I've just seen an 18 week old newfoundland with 3 small, firm, white masses on the lip, left side at the commisure.

They look like papillomas but I'm not sure there is a papilloma virus in dogs in the UK, and this dog is UK bred. I've never seen anything like them previously so any suggestions as to what they might be would be most welcome. Otherwise it'll be sedate and biopsy!
