Thank you all so much for your kind words and advice. My husband and I have discussed it and we do not feel that amputation is an option because it is not a cure. This has been a very rough weekend. On Friday, we did a biopsy. I gave her pain medication as prescribed. Friday evening she began to get very restlesss. She would not sit down she was panting and her heart was racing. I called the emergency vet and they said to give her another half dose of the pain medication and call back in two hours. Two hours later she was lethargic, shaking, moaning and groaning so I took her in.
They indicated that she could be having a reaction to the medication or the pain was just so intense it was causing her that much discomfort. He felt it was the later so, he placed a Fentynol (sp) patch and gave me additional medications for pain and sedation. It did calm her down some but the shaking did not stop. I was up all night sitting with her and called her vet on Saturday. Let me just say this, I asked the vet if it was ok to give so many medications to her at one time and if one of the possible issues she was having was a reaction to that medication. I offended them and was told by the vet tech 'that he was the doctor and did know what he was doing". My doctor said it sounded like the medication and that I should no longer give her the one that she was first on and that additionally, the Fentynol was so powerful it may be too much for her and I had the option of stopping this also (leaving her with no pain medication). By last night she could not stand up, we had been giving her water by using a medicine dispenser. It was aweful. I removed the patch.
By this morning she has come around but she is really having trouble with the leg. I am holding out hope that it is a fungal infection but I am realistic in knowing the the likelihood is cancer. If this is the case we wil let our lovely 'little' girl go on Tuesday. I can't bear to see her suffer. I love her too much.
Thank you all for your support.
