Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed
My 15 year old dog was prescribed Tramadol about 4 weeks ago for neurological pain relief. She has been on many medications for years for heart murmur. Also Denosyl for liver. 14 days ago she was a very happy, energetic, good appetite cavalier. 7 days ago she lethargic and wouldn't eat her breakfast. I took her straight to the vet and they did blood tests and said her kidneys were struggling. They set up IV fluids and after 4 days they told me that I had to euthanase her. did Tramadol do this?
