OK, so I feel sort of foolish today for calling the vet, but I was concerned. Maggie got spayed last week Wednesday & on Saturday I noticed a lump underneath the suiture (sp?) line. So I decided just to keep an eye on it, it had gone down at all by this morning so I decided to call. The vet asked me if it was hard & if there there was any drainage from the stitches? It is hard & there is no drainage and she is eating & acting fine. The vet explained that this is normal & this happens when the two sides are starting to grow back together. She was perfectly nice but I felt sort of foolish for worrying so much.
