I have a 16 year old female Pomeranian named Pumpkin who bites herself and has sores on her body.?

You need to take her back to the vet and tell him that the medicine only worked for a while,nd you have hear so much about prednisone, I think you will find its better to let her finish the whole percription also take to your vet about changing her diet because it might to strong for her now and she might need a adult food.You must find some relief for her she is in pain along with the itching. I had a Jack Russel that did tr he same way and I got her on a better food and she now is great, no scratching or crying.She might not have fleas but she could be allergic to fleas and if one got one her and jumped off. That is what was wrong with my little dog and after I changed her food and she finished her medicine,she was fine.Good luck!!!!!!
