A elevated reading on the protein parameter should always be followed up. Abnormal levels of protein spilling into a dog (or cat’s) urine can indicate kidney problems and/or infection.
But there are some other possible causes that should be considered first. A high-protein diet can cause a higher reading. Also, strenuous activity can cause a positive protein reading.
These are some of the reasons why we recommend that people test their pets about the same time of day each month. Morning is best before other factors can influence test results.
My cat Belle always tested a bit high (trace results) for protein because of her diet. Our vet told me to note each month and let him know if it ever went above the trace reading….which it never did. It was great to be able to keep such a close eye on her test results each month.
