Hi Nicolette,
To find a food suitable for your pup I recommend that you go back to your vet and ask what phosphorus level she would like to see in the diet. In other words have her define “low” for you.
AAFCO requires phosphorus levels that are higher than the diets formulated specifically for kidney patients. The phosphorus levels in the kidney diets differ depending on company and formula but can be about .5-0.8 grams phos/1000kcals. For diets you can buy in the store without a vet oversite the min is currently 1 gram/1000kcals recently changed from 1.4 grams/1000kcals. Most diets greatly exceed this and companies only report their min and not average phos level.
In general the Hill’s company is renal proactive and their senior diets are formulated to be close to the old min of 1.4 grams/1000 kcals. Most of their diets include grain. They make a Salmon and potato grain free and the phos level in that is reported as ~1.6 grams/1000kcals
Your may have to switch to meal feeding your dogs to best meet the nutritional recommendations from your vet.
