Clumber Spaniel puppies are heavy-boned flushing dogs with a melting expression. Your growth chart belongs with weight honesty, ear care, and exercise that respects growing joints in a substantial frame.

Clumbers gain weight easily; the chart plus waist photos matter.
Coat and dewlap can hide early gain; hands-on ribs monthly.
Brachycephalic heat risk varies; panting sets exercise windows.
Drop ears trap moisture; learn normal versus urgent.
They can be sound sensitive; socialization sub-threshold.
Teen listening dips are normal.
Puppyhood is not one stage. It is a stack of different problems and wins. Use this like a timeline, not a rigid rulebook.
Routine, trade games, gentle exposure.
Leash skills before pulls win.
Channel drive; protect joints.
Endurance builds gradually.

Clumber Spaniels were developed among British nobility as slower, methodical spaniels able to push through thick cover with strength rather than speed.
They are the heaviest spaniels; easy keepers in pet life if portions drift.
Modern Clumbers need training and grooming; boredom becomes noise and chewing.
The calculator uses your puppy's current age and weight to estimate adult size. Because puppies grow fastest early on and then slow down as they mature, the estimate adjusts for the stage of growth your Clumber Spaniel is in.
Clumber Spaniels are usually close to full size by around 18 months. As your puppy gets older and more of its growth is already complete, the estimate usually becomes more reliable.
Most adult Clumber Spaniels fall within a typical weight range of 55-85 lbs. You can use the calculator for younger puppies, but estimates are usually more accurate after about 12 weeks.
