Tailored Nutrition for Spayed & Neutered Puppies, Kittens, Adult Dogs & Adult Cats




Tailored Nutrition for Spayed & Neutered Pets

Our approach to pet food is purposeful, scientific and intentional. After spaying and neutering, pets have a reduced caloric need, an increased appetite and a decreased metabolism. All six formulations of VETERINARY HPM® Pet Nutrition for cats and dogs are formulated for these specific nutritional needs. Our diets include a careful composition that meets their new reduced calorie needs, while supporting satiety. Products include Junior formulas to support growth for your puppy and kitten patients, as well as Adult formulas to help patients maintain body condition throughout life. 

Our Approach


A New Composition, a New Approach

When it comes to spayed and neutered pets, it has been shown that dogs and cats fed a high-protein, high-fiber diet have less weight gain and less change in body condition vs. those fed standard adult wellness diets.1



Protein helps the pet feel fuller for a longer time. It also boosts energy expenditure, favors lean body mass over fat mass and helps with enzyme production.2 But all proteins are not equal. Learn more about why the source of protein matters from expert nutritionist Laura Gaylord, DVM, DACVIM (Nutrition)

Digestibility determines how much of a protein source a pet actually receives from its food source, and what nutrients (amino acids) are delivered to the body. Animal proteins, as discussed here tend to be more digestible than plant proteins.3 They also provide the pet with more essential amino acids, including those that support appetite control.3



There’s been a lot of research about fiber published within the past decade.4–6 Much of it demonstrates or confirms the benefits of fiber in weight maintenance and healthy digestion in pets. For example, fiber helps to stimulate normal gut functions,6 normalize gut motility and intestinal transit time in dogs and cat,5 and improve stool consistency.3,7

Fiber also helps address the spayed or neutered pet’s increased appetite by helping the pet feel full for a longer time,3 while decreasing caloric density.8 We took these benefits into account when we selected the fiber blend for our pet food. We have included an intentional mix of soluble and insoluble fibers in VETERINARY HPM Pet Nutrition.

Feeding Guidelines


What Makes This New?

Until now, dietary recommendations post spay or neuter required a choice between appropriate calories and adequate nutrients. The commonly used strategies for managing dogs’ and cats’ weight post-procedure leave pets at risk for hunger, inadequate nutrients and, in pets that are still growing these nutrient deficiencies can lead to problems with growth and development. See why

With VETERINARY HPM® Pet Food, you no longer need to make that unfortunate choice. Junior diets nourish growth and development in puppies and kittens while avoiding excess calories. Adult diets continue supporting spayed and neutered pets with precise feeding guidelines to foster an optimal body weight.
