How big will my Springer Spaniel get?
A fully grown English Springer Spaniel typically weighs somewhere between 18 and 25kg, standing around 48 to 51cm at the shoulder for males and a little less for females, and most reach close to their adult size by around twelve months old, though as an active, muscular gundog breed, they can keep filling out slightly for a few months after that.
Reading a Springer's growth curve
Springer Spaniels grow at a fairly steady, moderate pace compared with giant breeds, without the dramatic late-stage filling out seen in some larger gundogs. Most of their height is reached by around nine to ten months, with the last of their adult muscle and body shape settling in over the following couple of months.
Because Springers are a working gundog breed at heart, even pet-line dogs tend to carry a leaner, more athletic build than a lot of other breeds of similar height, which is worth keeping in mind if you are comparing your Springer's weight to a generic chart rather than one built around the breed specifically.
What affects where a Springer sits in that range
Working-line and show-line Springers can differ a little in build, with working dogs often slightly leaner and more athletic at a given weight, reflecting what they were bred to do day to day. Neither build is more correct — they simply suit different lifestyles.
Sex accounts for a meaningful part of the variation too, with males typically toward the top of the 18 to 25kg range and females toward the bottom, though individual variation within either sex is still fairly wide.
When a Springer's weight is worth a second look
Springers are an active breed that can gain weight quickly if their exercise drops without a matching adjustment to food, and because they are also known for being enthusiastic, food-motivated dogs, weight creeping up gradually is one of the more common issues owners run into as the dog gets a little older or less active.
A Springer that is losing condition, looking ribby, or showing a drop in energy alongside any weight change is a different matter, and that combination is worth mentioning to your vet rather than assumed to be normal variation.
Common questions
- How much should an adult Springer Spaniel weigh?
- Most adult English Springer Spaniels weigh somewhere between 18 and 25kg, with males typically toward the higher end and females toward the lower end. As an athletic working breed, a healthy Springer usually carries a leaner build than some other breeds of a similar height.
- When does a Springer Spaniel stop growing?
- Most reach close to their adult height by around nine to ten months old, with the last of their muscle tone and body shape settling in over the following couple of months, which is a fairly moderate pace compared with larger or giant breeds.
- Why is my Springer Spaniel gaining weight as it gets older?
- Springers are active, food-motivated dogs, and weight often creeps up gradually if exercise reduces without a matching adjustment to portion size. Checking body condition regularly and adjusting food to match your dog's current activity level helps keep this in check.
