So we were just stroking our cavapoo and felt this - not a great pic but it's black and raised.
It must be quite new - he was groomed second week in Dec and we would have definitely have seen it.
I am concerned. I've jumped to cancer. He's had cancer before (anal sac cancer), earlier last year.
We'll obviously get him to a vet on Tuesday (we are abroad for the weekend).
He's 11 in May.
Thanks
