Is your pet food bag lying to you?

Generic feeding charts at shops like Maxizoo are often wrong. Your pet needs a bespoke plan, not a broad average.

The 'One Size' myth is failing Irish pets

Bag guidelines are broad averages for 'active' dogs. But a Dublin apartment dog doesn't need the same fuel as a working Collie in Wicklow.

Neutering changes the math entirely

After a spay or neuter, a dog's metabolism can drop significantly. The bag's instructions don't change, but your pet's calorie needs do.

Meet RER: The Baseline for Health

Resting Energy Requirement (RER) is what your pet needs just to breathe and digest. It is their unique metabolic starting point.

4 / 10

The Formula (It’s easier than you think)

RER = 70 x (body weight in kg)^0.75. Use your phone's calculator to find this baseline before factoring in the day’s adventures.

5 / 10

Adjust for the Wild Irish Weather

Shorter walks during a rainy winter mean fewer calories. Hiking the Galtees in summer? They will need a significant fuel boost.

6 / 10

Choose your multiplier wisely

Most neutered pets only need 1.6x their RER. However, active outdoor cats in rural areas might require significantly more energy.

The 11kg Westie Reality Check

This typical dog needs roughly 675 calories. Bag guidelines often suggest 20% more. That surplus leads to serious weight gain over a year.

Trust the Ribs, not just the Math

Biology isn't a spreadsheet. You should feel the ribs easily under a light layer of fat. If you can't, it is time to reduce the portion.

The 10% Rule for Treats

Love isn't measured in scraps. Treats and Sunday roast bits should never exceed 10% of your pet's total daily caloric allowance.

10 / 10

Beware the 'Hidden' Calorie

One dental chew or a spoonful of peanut butter can be 100 calories. For a small dog, that's 20% of their entire day in one go.

This isn't about food. It's about longevity.

Managing calories isn't about restriction; it's about adding years to their life. A healthy weight means more adventures in the Phoenix Park.
