Detailed Rhodesian Ridgeback growth profile

Breed Overview

The Rhodesian Ridgeback is a powerful and athletic breed originating from Southern Africa, where it was developed to track and help corner lions. Known for the distinctive “ridge” of hair along its back growing in the opposite direction, this breed is both striking in appearance and noble in temperament. Ridgebacks are intelligent, independent, and loyal, making them excellent family companions when given proper training and socialization.

Size Category: Large.
Growth tracking is especially important for Rhodesian Ridgebacks because their rapid development during puppyhood can put strain on joints and bones. Keeping their weight within healthy ranges helps prevent orthopedic issues like hip dysplasia, which the breed can be prone to.

Most Rhodesian Ridgebacks reach 50% of their adult weight by around 6 months.
Rule of thumb: Double their weight at 16 weeks to estimate adult size.

Note: They generally reach full height between 12 and 15 months, but may continue to fill out in muscle and body mass until 18–24 months.

Rhodesian Ridgeback Growth Tips

Nutrition

• Feed a large-breed puppy food until about 18 months to support controlled, steady growth.
• Offer 3 meals per day until 6 months old, then reduce to 2 meals daily.
• Avoid overfeeding, as excess weight can stress developing joints.

Exercise

• Provide daily walks and low-impact play.
• Avoid forced running, jumping, or long-distance activities until after 18 months.
• Incorporate mental stimulation through training, scent work, or puzzle toys.

Health Watch

• Watch for hip and elbow dysplasia, especially if there’s a family history.
• Monitor for bloat (gastric dilatation-volvulus), a risk in deep-chested breeds.
• Maintain a lean body condition during growth to support long-term joint health.
