my 2 year old Daschund was spayed last month about 2 weeks after the spaying she starting limping and then she got all these sores in her ears , on her nose and her back so i took her back to the vet he said she must have got into something and some kind of bugs or something got under her skin the assistant suggested staff infection...they put her on clindamycin 25 mg two times a day...she seems to be doing a lots better in her ears and on her nose but not on her back but now her back legs seems to be stiffening up on her again....b4 the surgery she was a happy go lucky nothing ever wrong with her kind of puppy could this all be related and what could be wrong and what should I do?
