Are sub-q fluids safe for dogs with kidney failure and breathing?
If a dog has heart problems and is unable to utilize the volume of fluids that is given, those fluids can end up in the lungs and cause an increase in breathing. This is most common with large amounts of fluids given IV quickly, but can occur with SubQ fluids. However, it takes time to develop, so it would have occured a number of hours after fluids were given - not immediately after. And when Memi was hospitalized, the IV fluids should have made her worse, not better. The most likely explanation is that the breathing was due to her kidney disease, and the fluids were coincidentally given at the same time. Giving enough fluids (IV or SubQ) is very important to making a kidney failure patient feel good, so continuing her SubQ fuids is important.
Good luck! I hope that answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.
