Four key facts about animal obesity

While we all love a pet with character, a chubby dog or cat isn’t always something to smile at. What some pet owners might think of as ‘rounded’ may actually be animal obesity… and it’s something that could be a sign of, or lead to, serious health issues.

At VETaround, our mobile vet sees clients every day who love and adore their animals, but who aren’t always aware that an extra kilogram or two in weight could actually be causing harm.

We know that your pets mean the world to you. As an owner, it’s up to you to play your part and look after them as best you can. So here’s our guide to animal obesity and the four key facts you should know.

You may not know your animal is obese


It’s surprisingly common for pets to suffer from weight gain and obesity, so much so that many pet owners aren’t even aware their pets are obese.

If you’re unsure, one way to check is to take a good look at their shape. With dogs for instance, in most cases you should be able to see their waist when viewed from above, feel their ribs if you push gently along their ribcage (they should have some fat covering this area), and their abdomen should be taught and not hanging down.

We would also recommend you talk to our mobile vet who can give you the recommended healthy weight range for your animal’s age and breed. It’s the best way to confirm if your dog, cat, bunny or any other pet is at their optimum weight.

“Excess weight in pets isn’t just about appearance—it can contribute to serious health issues including diabetes, arthritis and reduced mobility.”

There are various factors - and one key cause


There are quite a few factors that might lead to weight gain in your pet.

In some cases, it could be a symptom related to an underlying health issue. Some breeds including dachshunds, beagles and basset hounds may be more prone to weight gain. Desexing can contribute to weight gain in pets because once a pet is desexed they need less food day-to-day. However, the health benefits of desexing are substantial for many pets. Each case is different so ask us for advice if you’re unsure how this applies to your pet.

Hands down the most common cause of animal obesity is overfeeding. It’s very easy to forget how small their tummies are and how little food your pet really needs. That’s why it’s very important to read the instructions on pet food carefully, or to speak to our home visit vet to get a tailored feeding plan that best suits your furry friend.

Animal obesity is a problem


Animal obesity isn’t just about appearance. It can have a flow on affect, and that’s where the problems really lie. To start with, excess weight will make it harder for your pet to exercise, which only makes the issue worse.

Crucially, excess weight in dogs, cats and other family pets may lead to serious issues including heart failure and diabetes. It can contribute to issues including arthritis, urinary tract problems, skin conditions, poor general health and lethargy. Obese pets are also at greater risks of side effects associated with anaesthesia and surgery should they need an operation.

Above all, overweight animals aren’t going to feel their best. We all want our pets to be healthy and happy, so it is important to stay on top of weight management.

“Overfeeding is the most common cause of animal obesity, often without owners realising how little food their pet actually needs.”

Key Takeaways


  • Pet obesity is often overlooked

    Visible waistlines, rib feel, and abdominal shape can help identify whether your pet is within a healthy range.
  • Overfeeding is the most common cause
    Even small excess portions can lead to weight gain over time, especially if feeding guidelines are not followed closely.

    Certain breeds and desexed animals may require adjusted feeding to maintain a healthy weight.

Frequently Asked Questions


How can I tell if my pet is overweight at home?

You can assess your pet’s shape by looking for a visible waist from above and checking if you can feel their ribs with light pressure. Their abdomen should not hang down noticeably. These are general indicators, but a mobile vet can confirm a healthy weight range based on your pet’s breed and age.

What causes weight gain in dogs and cats?

Weight gain can be influenced by several factors, including breed tendencies, desexing, and underlying health conditions. However, overfeeding is the most common cause. Even small excess portions over time can lead to noticeable weight gain.

Can desexing cause my pet to gain weight?

Desexing can reduce your pet’s daily energy needs, which means they may require less food than before. If feeding amounts are not adjusted, weight gain can occur. A home visit vet can help you understand how to modify feeding after desexing.

Why is animal obesity a serious health issue?

Excess weight can make it harder for pets to exercise, which often worsens the problem. It may also contribute to conditions such as diabetes, arthritis, urinary issues and heart problems. Overweight pets can also face higher risks during anaesthesia and surgery.

Can a mobile vet help manage my pet’s weight?

A mobile vet can assess your pet’s condition and provide tailored nutritional advice based on their needs. They can also create a structured weight control program and monitor progress during follow-up or annual health checks. This allows for ongoing adjustments as your pet’s condition changes.

What does a weight management program for pets involve?

A weight management program typically includes a step-by-step plan for controlled weight loss. This may involve adjusting feeding portions, recommending suitable products, and monitoring progress over time. Regular check-ins help ensure your pet is moving toward a healthy weight safely.
