Animals – Dealing with pudgy pets

Did you know that giving your dog just one slice of cheese can be the calorie equivalent of you eating a whole Big Mac? As a veterinarian, one of the most common (and preventable) issues we see is obesity in pets. While it can be easy to overlook a chubby cat or call a round dog cute, the reality is that excess weight can have serious effects on your pet’s health and quality of life.

In New Zealand, it’s estimated that around 40 per cent of dogs and cats are overweight or obese. Just like in people, being overweight increases the risk of many health problems including arthritis and joint pain, diabetes (especially in cats), heart and breathing issues, skin infections and reduced lifespan.

Even a few extra kilos can put added stress on joints and internal organs, affecting your pet’s energy levels, comfort and ability to move around easily.

What causes obesity in pets?

It’s usually a combination of too much food and not enough exercise. Free-feeding (leaving food available all day), table scraps (often too rich and fatty for pets), high-calorie treats, lack of portion control and reduced activity are the most common factors. Older pets and those kept mostly indoors are especially prone to weight gain. Neutered pets also have lower energy needs and require fewer calories.

A healthy pet should have a visible waist when viewed from above, a tucked-up belly from the side, and ribs you can feel easily, but not see. Many pets don’t act “full” even when they’ve had enough – they’ll happily eat more if it’s offered. If you’re unsure, your vet can assess your pet’s Body Condition Score and help determine a healthy weight range.

Feeding routines play a big role in addressing obesity. Pets thrive on structured mealtimes, which help regulate appetite and metabolism. Instead of free-feeding, serve measured meals once or twice daily depending on the animal. Avoid letting them graze all day, as this often leads to overeating. Use a measuring cup or scales to portion food accurately. Cut back on treats and avoid feeding leftovers or human food.

Adding more activity also helps – walks, playtime, food puzzles or interactive feeders. Weighing regularly can help track progress and guide the next steps in your pet’s weight management.
Keeping your pet at a healthy weight is one of the best ways to improve their comfort, mobility and overall wellbeing. It’s not about making them skinny – it’s about helping them feel their best and stay healthy for years to come. If you’re concerned about your pet’s weight, talk to your vet – we’re here to help.
