Veterinary Nutritionist Advises Slow Transition to Kidney

A veterinary nutritionist is advising veterinarians on how to help pet owners switch their animals to prescription kidney diets without resistance. Dr. Caitlyn Getty, DVM, PhD, DACVIM (Nutrition), stresses that the over-the-counter foods many pets currently eat can be actively harmful for renal patients.

Getty explains that the first step is convincing owners of the critical need for the change. She notes that standard pet foods are often high in phosphorus, a substance known to worsen kidney disease. In contrast, therapeutic renal diets are formulated to be low in phosphorus and have controlled protein levels. Some also contain targeted support ingredients, such as AB+ Kidney Defense. Staying on an inappropriate diet, she argues, has negative effects on the animal's health.

The Case for a Slow Transition

Once an owner understands the medical necessity, the focus shifts to the practical transition. Getty emphasizes that a slow, patient approach is not only acceptable but preferable. The goal is to get the pet fully onto the beneficial nutrition, and a rushed process that leads to food refusal is counterproductive. She advises veterinarians to have a "big conversation" with owners about extending the timeline.

A transition period of two to three weeks can be a starting goal. If the pet resists, Getty says it is perfectly fine to extend the process over a month or even two. "In the end, getting them onto that beneficial nutrition is going to be really, really, really important," she states in the interview with dvm360. Taking longer to achieve a successful switch is better than having the pet reject the new food entirely and remain on the harmful original diet.

Counseling the Concerned Owner

A key challenge is managing owner expectations and anxiety. Getty acknowledges that owners heavily gauge their pet's wellbeing by whether the animal eats its food. This can make them reluctant to push a dietary change if the pet seems unhappy. She advises veterinary professionals to validate this concern while reinforcing the long-term health stakes.

The conversation should balance empathy with medical facts. The veterinarian must explain that while the transition might be challenging, the consequences of not switching are more detrimental. Getty's approach centers on partnership, setting a flexible plan that reduces stress for both the pet and the owner.

Comparing Diet Impacts

The core of Getty's argument rests on the fundamental differences between over-the-counter foods and prescription therapeutic diets for kidney disease. The following table summarizes the key contrasts as presented in her discussion:
