Hi Mary , I'm James DVM MRCVS and would like to help you with your question
Lets have some more info of this mass . does it bleed or has an ulcerated point to it?
after you touch it (if you did) does it get larger or more irritating for Trixie?
Is Trixie otherwise fine , eating and drinking fine , no coughing or weight loss?
Hi Dr.J - We have taken Trixie to our vet here in Dublin, and she needs to have this growth removed.
Thanking you, bye Mary
