My dog has end-stage kidney failure & PH. How to prioritize care?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | neutered | 13 years and 11 months old | 5.4 lbs

Hi. My dog was diagnosed with kidney failure (end stage) a few weeks ago. After a trip to the emerge he was diagnosed with pulmonary hypertension as well. Would treating the PH be a good idea when his Kidneys are so compromised/fragile? Would there be contarindications dealing with both at the same time? Would sub-q fluids affect the PH or the meds for PH. I'm just not sure what to prioritize or if both can and should be #1. Thanks.

Thank you for your question. Unfortunately, if Memi has been diagnosed with end stage kidney failure, then all you can do is try to keep him comfortable and hydrated the best you can. Depending on the degree of pulmonary hypertension, and any other existing heart problems, aggressive subcutaneous fluids could be dangerous, however without fluids, he will likely rapidly become dehydrated. That is a difficult balance. You could try splitting up the fluids, and administering smaller volumes more frequently instead of one larger bolus. But this is definitely a discussion to have with your veterinarian who will be much more familiar with the details of Memi's condition. Thank you for using Petco Pet Education Center, formerly Petcoach.
