I have had a really confusing time with the treatment of my dog Cassie. She is a 14 year old lab/coonhound cross. She had sores on her front left paw that the vet kept saying very nothing, just harmless growths/ They grew and another one popped up on her shoulder area. I took her out of country to Canada to where I live ( she was living in Nevada at our farm).In Canada they said she needed and operation to remove the lumps and sent me to a specialist. The specialist said he could try to remove the shoulder lump but the one on the paw had no skin to cover it. He did not explain any thing beyond telling me since she is old he would not recommend amputation. She had the should lump removed but when she was released without a cone or any covering, her paw started bleeding and got infected.I sent pictures of the infection to the vet but they did nothing. I took her back for 2 weeks every 2nd day and they re bandaged her paw but she was still limping.During this time I asked for results of blood tests or an explanation of why, but it was not forthcoming. I took her to another vet who could not understand why the leg was not amputated instead of the costly useless surgery and she had her amputation and was doing well. She then had an infection at the incision site so I took her to an emergency vet clinic( the oozing started at night). They gave her antibiotics and pain killers and and did chest x rays and tested the inflammation to see that she had the right antibiotics. She is doing OK now, but I have been reading information on this blog and I am wondering why she would not be given chemo and if there is anything else I should do. She is eating but she now prefers BBQ chicken. She walks and wags her tail a lot. She was not  doing this after the surgery to remove the should lump as she was still in a lot of pain. Thanks for any information or help.
