ASK-THE-VET: KIDNEY AND URINARY TRACT HEALTH IN DOGS
February 1st, 2010 by Dr. Donna Spector
Question: My dog, who has no history of urinary problems, was recently diagnosed with mineralization of the renal pelvis bilaterally. This diagnosis was made from a CT scan for an unrelated issue and was later followed up by a negative urine culture, so we do not have any more detailed information about what exactly caused the mineralization. Our vet suggests switching to a prescription diet with these ingredients:
RICE, GROUND CORN, CHICKEN FAT, CHICKEN MEAL, CORN GLUTEN MEAL, NATURAL FLAVORS, DRIED EGG POWDER, SODIUM CHLORIDE, CELLULOSE POWDER, POTASSIUM CHLORIDE, DICALCIUM PHOSPHATE, CHOLINE CHLORIDE, CALCIUM CARBONATE, CALCIUM SULFATE, TAURINE*, VITAMINS [DL-ALPHA TOCOPH should also mention that oEROL ACETATE (SOURCE OF VITAMIN E), BIOTIN, D-CALCIUM PANTOTHENATE, NIACIN, PYRIDOXINE HYDROCHLORIDE (VITAMIN B6), VITAMIN A ACETATE, VITAMIN D3 SUPPLEMENT, THIAMINEE MONONITRATE (VITAMIN B1), VITAMIN B12 SUPPLEMENT, RIBOFLAVIN (VITAMIN B2), FOLIC ACID], TRACE MINERALS [ZINC OXIDE, FERROUS SULFATE, COPPER SULFATE, MANGANOUS OXIDE, SODIUM SELENITE, CALCIUM IODATE], PRESERVED WITH NATURAL MIXED TOCOPHEROLS, ROSEMARY EXTRACT, AND CITRIC ACID.
I know that this prescription diet is designed to increase water intake in the dog, increasing the volume and frequency of urination, but it appears low quality to me. Instead, I am considering switching from Spot’s Stew dry to canned food, to increase the water content of the food, along with getting him to drink water more frequently, which we can usually do by encouraging him and offering fresh water. What do you suggest? Thank you!
Answer: Increasing water intake is undoubtedly one of the most important treatments to promote kidney health and to prevent canine urinary stones! Drinking more water produces dilute urine. Dilute urine contains less concentrated minerals so they are less likely to form calcification and then stones.
You can increase your dog’s water intake by feeding canned food. Some dogs will drink more voluntarily if a pet-designed continuous water fountain is used. Also try large bowls placed around the house in all of your dog’s favorite places. The addition of light salt (potassium chloride) to your pet’s food can also effectively increase the amount of water they take in.
Hope that helps.

Hi. We are going through the same thing–can she drink all natural brotas a secondary way to increase her h20 intake?

Hi Susan,
Yes you can give your dog all natural broth as another way to increase fluid intake–the best choice is a low-fat, low-sodium variety. The other ways to increase your dog’s water intake include feeding canned food, using pet-designed continuous water fountains, multiple bowls in varied locations around the house and the addition of light salt (potassium chloride) to her food.
Hope this helps.

I have a 10 month old Siamese male kitten that all of a sudden does
not want to use the toilet to urinate. He also seems like he has a
hard time pooping, he strains. I feed him Eagle Pack Holistic Select
Chicken formula for Cats and Kittens. One of my students recommened
Halo chicken dry food for indoor cats. I tried wet food but he does not
like it much. He seems like he is drinking enough water though the day.
Any suggestions?
Thank you,

Hi Georgann,
Thanks for writing in. The reason your cat may not want to use the litterbox to urinate may be one of a few reasons. Many cats that experience painful defecation or constipation will shy away from the box for urination as well because they recall it as a “bad” or painful place. The Halo dry food can be an excellent choice for pets with constipation as it contains fiber-rich vegetables, prebiotics and probiotics to support intestinal health. See my article about natural remedies for constipation in cats at http://www.halopets.com/pet-education/pet-articles/natural-remedies-for-constipation.html.
The other very common urinary ailment of cats is a condition called interstitial cystitis. This is a sterile inflammation of the bladder that causes pain and avoidance of the litter box. Increasing water intake (try fountain waterers, etc) and enriching their home environment (see http://www.indoorcat.org) can help with the condition dramatically. You should see your veterinarian to make sure he doesn’t have issues like stones or other bladder problems.
Good luck.
