question about dog food for my sick dog..?
My dog was diagnosed with renal insufficiency last week. The vet suggested a food called canine k/d. but the problem with that is it is very very expensive. I love my dog, he is my baby. Now here is my question. He also said that I can find other dog foods that are lower in protein (less than 20%), and lower levels of phosphorus, sodium, and potassium. I have been looking at dog food labels all weekend both in stores and online. I cannot figure out what is considered low phosphorus, potassium and sodium. They don’t generally give a percentage, nor can I find anything online about what a recommended percentage is for a healthy dog for me to compare to (what a healthy dog would have vs. a dog with kidney problems). Anyone have any ideas or suggestions other than calling the vet? He is not in on Monday’s unless its emergency care. Thanks.
Hills k/d
Protein: 14.7%
Fat: 19.4%
Phosphorus: .24%
Sodium: .23%

Here is a great article about phosphorus and protein in dog food:

I highly doubt you will be able to find a commercial dog food that has similar levels as Hills k/d. Part of the reason is that in order for a dog food to be certified as a complete balanced diet by the AAFCO, it must meet minimum standards for the well being of healthy dogs.
Prescription diets are prescription because they have nutrient levels that are either too high or too low for normal dogs to stay healthy. This is why you can only get prescription food from a vet. A prescription diet could make a healthy dog sick.
I encourage you to research kidney problems and diet in dogs. You will find a lot of contradictory advice and opinions, even among vets.
Although I am not a vet, my job is related to animal nutrition. From my research and experience, ingredients play a big part in dog diet, not just the nutrient analysis of the food. For example, protein can come from both meat and grains. Grain protein has a low digestibility and is only 50%-75% usable by a dog’s body. Meat protein has a high digestibility and is 90%-95% usable by the body. It is safer to feed a food with protein coming from meat and best to avoid protein coming form grain.
Water is another very important factor in kidney health. A dry food diet concentrates nutrients and can allow them to build in places like the kidneys unless there is enough water to flush them out. A diet with a high water content, like a canned food or raw meat diet, will more evenly distribute proteins and nutrients throughout the body and help prevent kidney and bladder problems.
There are also supplements on the market that help support kidney health. A very good one is Wapiti Labs Renal Formula. It is very reasonably priced too.
What is considered to be low protein and nutrient levels varies by your dog’s life stage. Generally speaking, 20% or less for protein and .7% or less for phosphorus.
If you want to switch off of prescription, I would look into the following brands to find something that works for your dog. The websites for these companies usually have very detailed nutrient information available.
Innova (Natura)
Natural Balance
Wellness
Go! Natural
Solid Gold
Canidae
