if shes to ill to take to the vets get them out they will come but might cost a bit. if shes not strong enough to get to the vets there is defiantly nothing you can do at home for her. could be 100's of different things from a infection, cancer, poisoning, something stuck in her throat, age, heart defect and many more but dont worry to much could just as easily be something simple and nothing to worry about but only a vet or experienced person that see's the dog will be able to examine her and say for certain. top and bottom of it is you can stay at home and cross your fingers that she will get better or get to the vets asap.
