Thank you all for your good wishes for Samantha. The vet called today with the biopsy results. The lump that was removed was a tumour, but not malignant. We had been very worried, because Samantha has developed another lump between her shoulder blades, but as the vet pointed out, that is where she would have been injected and she has possibly had a reaction to that.

She goes back soon to have her stiches out, but in the meantime she is being a very good girl and taking her antibiotics without complaint. When we are both with her in the evening we take off the cone so that she can groom herself, and she doesn't complain when it goes back on again overnight. She is being a complete sweetie!
