Field Spaniel Growth Guide

Breed Overview

The Field Spaniel is a rare, versatile sporting breed originally developed in England for fieldwork and retrieving game. Bred to be slightly more substantial than the English Cocker Spaniel, the Field Spaniel is known for its gentle nature, intelligence, and affectionate loyalty. Despite being an excellent hunter, this breed is equally at home as a calm, devoted family companion.

Field Spaniels fall into the medium-size category, typically weighing between 35 and 50 pounds as adults. Because of their steady but not rapid growth pattern, tracking your Field Spaniel’s weight during puppyhood is important to avoid developmental issues. Balanced growth ensures strong bones, healthy joints, and long-term well-being.

How Much Bigger Will My Field Spaniel Puppy Get?

Field Spaniel puppies usually reach about 50% of their adult weight by 4 to 5 months of age. Growth continues steadily, with most dogs reaching close to adult size by 12 months, though they may fill out in muscle and chest size through 15–18 months.

Rule of Thumb:
To estimate adult size, double your puppy’s weight at 16 weeks.

Unlike giant breeds that grow for up to 2 years, Field Spaniels mature at a more moderate pace typical of medium-sized dogs.

Field Spaniel Growth Tips

Nutrition

A Field Spaniel puppy should be fed a high-quality, balanced puppy food designed for medium breeds:

• Feed 3 meals per day until 6 months of age, then transition to 2 meals daily.
• Avoid overfeeding to reduce the risk of obesity and joint stress.
• Choose foods rich in omega-3 fatty acids, glucosamine, and balanced calcium/phosphorus levels to support bone and joint development.

Exercise

Field Spaniels have moderate-to-high energy levels and require daily physical and mental stimulation:

• Keep exercise low-impact during the early months to protect developing joints.
• Focus on short walks, gentle play, and basic training sessions.
• Avoid excessive stair climbing or jumping before 12 months.

Health Watch

Field Spaniels are generally healthy but may be prone to:

• Hip dysplasia
• Ear infections (due to floppy ears)
• Eye issues, including retinal atrophy

Regular vet visits, weight monitoring, and maintaining a lean body condition help prevent stress on joints and reduce long-term risks.
