Trying to make the best decision for my dog. She is a 12 year old shih Tzu and the most loyal lovely dog. I noticed Wednesday she had been bleeding a gooey substance from the back end. Vet saw her yesterday and said she had a small pyometra which is open and it was very beginning of it. (Massive infection in her uterus) She isn't unwell and her usual self. She said she would operate straight away as she didn't feel she was poorly or suffering and it could wait until tomorrow. She explained that it is a major operation and due to her other health issues with arthritis and her age I should consider what to do. She will not survive without the operation. She may not survive the operand if we do have the operation and it is successful it would be massive for her at her age. We hadn't had her spade before as we had her later on in life and we didn't want to put her through that at an older age also we had never known this could happen. (Regretting that decision now.) She is booked in for surgery in the morning but after speaking with family and friends they think it is cruel to put her through it. I love my dog and I really want what is best for her. I don't want her to be in pain. I want her later years to be comfortable her arthritis is getting worse and I do wonder if this operation will be too much. I need to decide what to do before tomorrow morning. Has anybody else had a pyometra operation on an older dog? Is it as awful as it seems? Would
