Hi all, our 5yr old lab cross has developed this rash on her tummy over the last week. It isn't bothering her at all, no excessive cleaning or scratching at all. The edges of the areas are soft but can be scratched away a little and not crusty like scabs. I took her to the vet when I noticed the first small, 5p sized one and then she thought it was a wound but now it's spread and obviously isn't. She's completely well in herself and up to date with booster/flea treatment/worming etc. Any ideas? Thank you!
