Summer Bodies: Why A Pet’s Weight Matters in the Heat
May 18, 2026
As the days get longer and temperatures rise in Northamptonshire, summer is the perfect time to get active with your pet; but warmer weather also brings increased physical demands. Extra weight can put strain on the heart and lungs, making your pet more susceptible to overheating, fatigue and even heatstroke.
Now is the ideal moment to check your companion is at a healthy weight, and in this article, our vets in Towcester explain how. You can also book an appointment with our nursing team at Towcester Vets to assess your pet’s weight.
Is your pet a healthy weight for summer?
Understanding Body Condition Score (BCS)
The Body Condition Score (BCS) is a practical way to assess your pet’s weight beyond the weighing scale. Rather than focusing on numbers alone, BCS encourages owners to feel the ribs and not just see the scale. Our team at Towcester Vets explain that a healthy pet’s ribs should be easily felt under a thin layer of fat, with a defined waist visible from above and a slight abdominal tuck from the side.
The perception gap
According to 2026 PDSA Pet Health Survey data, there’s often a perception gap between what owners believe is a healthy weight and the reality. Many pets carry extra pounds from the winter months –- the ‘winter coat’ of fat, which can go unnoticed. These extra kilos may not seem significant now, but they can dramatically increase the risk of overheating and joint strain when your dog or cat is more active during summer.
Why weight matters
Excess weight doesn’t just make your pet sluggish; it worsens joint problems, slows recovery from exercise and increases the risk of heart and respiratory issues. Towcester Vets’ share that even modest weight loss in an overweight pet can improve stamina, mobility, and overall comfort – helping them enjoy long summer walks, runs, or play sessions safely.
Tips to keep pets lean and active
- Short, frequent walks for dogs around Northamptonshire, gradually increasing distance.
- Interactive play for cats, encouraging movement indoors.
- Monitor portion sizes and reduce treats if needed.
- Regular weigh-ins and BCS checks to track progress.
