This episode explores obesity in dogs and cats — why it is one of the most common yet most harmful health issues seen in veterinary practice. It explains how to recognise excess weight, why it shortens lifespan, the medical conditions it contributes to, and how owners can help their pets safely return to a healthy body condition through feeding changes, monitoring, and understanding risk factors.
Podcast Summary: Understanding Obesity in Pets
- Obesity is extremely common — around 80% of pets seen in practice are overweight, and 30–40% are classified as obese.
- Weight on a scale is less important than body condition: pets should have a visible waist, a tucked abdomen, and ribs that can be easily felt under a thin layer of fat.
- Most obesity results from overfeeding — free-feeding dry food, excess treats, table scraps, food from children, or access to other animals’ feed.
- Energy-dense foods, highly palatable dry foods, and fatty meats make it easy for pets to consume more calories than they burn.
- Many owners consistently overestimate what is an appropriate portion size, especially in small dogs whose “tiny treat” is equivalent to a human eating a biscuit or even a block of cheese.
- Reduced activity, ageing, joint disease, and desexing all contribute to weight gain by lowering metabolism and decreasing movement.
- Some medical conditions — hypothyroidism, Cushing’s disease, liver disease — can predispose pets to weight gain, although these make up a small percentage of cases.
- Puppies and kittens must not be allowed to become overweight — excess weight during growth increases the risk of lifelong joint disease.
- Obesity shortens lifespan and dramatically reduces quality of life by worsening arthritis, increasing heat intolerance, causing exercise reluctance, and raising the risk of respiratory issues.
- Overweight pets are more prone to skin disease, infections, poor immune function, high blood pressure, heart strain, and metabolic diseases.
- Effective weight loss programs require owner behaviour change more than pet behaviour change — measuring food accurately, reducing portions, limiting treats, and reweighing regularly.
- A typical starting point is reducing the current measured food amount by 20% and reweighing every 2–3 months.
- Vets often provide body condition scores (0–9 scale), with 5 being ideal and 7–9 reflecting moderate to severe obesity.
- Forced exercise is not recommended for overweight pets with joint disease; instead aim for gentle, frequent, low-impact movement.
