Cocker Spaniels are affectionate, food-motivated dogs that are consistently flagged as one of the more obesity-prone breeds. The long coat and merry nature make it easy to miss the extra weight.
Ideal weight

| Cocker Spaniel | 12–15 kg (26–34 lb) |
An easy breed to over-love. Cockers are notably food-driven and among the breeds most prone to obesity. Their feathered coat hides body shape, so weight creeps up unnoticed, and excess weight worsens the ear, skin and joint problems the breed already tends toward. Feel through the coat rather than trusting the eye.
How to tell if your pet is overweight
- Feel, don't look. The thick coat hides weight, so press gently through it — ribs should be findable under a thin layer without digging.
- Look from above. There should be a clear waist tucking in behind the ribs; a straight or bulging outline means no waist.
- Check the side profile. The belly should tuck up behind the ribcage rather than hang level.
What to do about it
- Weigh the food, don't scoop it. Eyeballing portions is the most common cause of overfeeding.
- Count treats as calories — keep them under 10% of daily intake; swap biscuits for carrot or green bean.
- Build up daily activity gradually, switching to low-impact options like swimming if joints are sore.
- Reweigh monthly. Safe loss is about 1–2% of body weight per week; involve your vet for an overweight pet.
