I have a female chihauhua called Gracie and she was spayed back in the beginning of March this year. She still has internal stiches that you can see 5 months on as they have yet to disolve. Saturday night I notice a hard 5p sized lump just off to the left of one of the sutures you can roughly see though her skin. It doesn't hurt when touching and shes fine in herself. I've read alot about how it may just be the stiches, but as I've stated above it's been 5 months and surely it would of happened sooner? But then I'm also worried it could be a hernia? I'm taking her to the vets tomorrow but I'm just wondering what others may think it could be? Thanks!
