Hannah Zulueta Hyperkalemia is a potential complication of dogs with Chronic Kidney Disease (CKD). In a subset of CKD dogs, hyperkalemia can be associated with commercial renal diets and could restrict the use of these diets. Knowing these small details can help you as you prepare your dog’s kidney-friendly home-cooked or raw meals.
I’ve also included a column if you’re curious about the oxalate levels.
| Vegetable | Potassium mg per 100g | Oxalate mg per 100g |
| Cucumber | 136 | 2 |
| Cabbage | 170 | 6 |
| Green Lettuce | 194 | 2 |
| Asparagus | 202 | 24 |
| Green Beans | 211 | 17 |
| Collard Greens* | 213 | 34 |
| Green Peas | 244 | 45 |
| Celery | 260 | 7 |
| Zucchini | 262 | 6 |
| Turnip Greens | 296 | 45 |
| Broccoli | 300 | 62 |
| Cauliflower | 303 | 8 |
| Swiss Chard | 379 | 1008 |
| Brussels Sprouts | 389 | 36 |
| Dandelion Greens | 397 | 19 |
| Kale | 410 | 23 |
| Avocado | 485 | 0 |
| Spinach | 580 | 750 |
| Beet Greens | 762 | 610 |
*Collard Greens are very high in calcium and so I would pass on feeding collard greens to dogs with CKD.
A Word About Oxalates
Even though I’ve listed the oxalate content above, as of the time that I published this article I was not able to find any clinical studies on the upper limits for oxalates for dogs with CKD but I include the information just the same because a client of mine had asked me about it.
In humans, dietary oxalate may have an important influence on the risk of formation of CaOx kidney stones but we don’t know what the allowances are for dogs.
If you need help figuring out what to feed your dog, I’m available to help you formulate recipes. Visit my packages page to learn more.
I wish you and dogs good health.
