My 16 year old dog was diagnosed with kidney failure three years ago, and with Cushings in June this year.
He is having Fortekor 2.5mg for the kidneys and started 10mg Vetoryl for the Cushings, under close observation because it is not recommended for dogs with kidney failure. He became unwell after 6 weeks on it and I stopped it immediately. He is currently not being treated for the Cushings disease.
He had a blood test this week - Urea (33.2mmol/L) Creatinine (201.0 umol/L) Cholesterol (13.06 mmol/L) Potassium (6.27 mmol/L) Inorganic Phosphorus (2.38 mmol/L) All of these are increased since his last test two months ago.
He also had an ACTH - pre 95.2 nmol/L and post 596 mol/L
He seems well in himself and has a reasonable appetite, His Cushings symptoms seem to have almost disappeared although some days he drinks a little more water than normal, but not the massive amounts he used to.
I am worried that by not treating the Cushings, it is making his kidney problem worse. Could this be true? Or would it be even worse if the Cushings was treated?
