Hi, our Cockerpoo has recently started suffering from a build-up of dark a hard nodules on her nose and chin. When soaked they can go gummy and can be pulled off however, this has led to an increase in growth. We have seen the vet before lockdown and she wasn't sure what they were and offered us a hibiscus scrub but this hasn't worked. It seems to be bothering her as she has started rubbing her nose with her paws and on the doormat. We will try a different vet after lockdown, however, we are wondering if anyone has come across this before. Please see photos attached. Thank you for any help!
