To determine if a Cavalier King Charles Spaniel is at a healthy weight, you should be able to easily feel but not see their ribs without pressing hard, and they should have a noticeable waist when viewed from above. A slight abdominal tuck should also be visible from the side. Maintaining a healthy weight is crucial for preventing health issues, especially considering their predisposition to certain genetic conditions.

When do Cavalier King Charles Spaniels Stop Growing?

Cavalier King Charles Spaniels reach their full-grown size and physical maturity at around 12 to 15 months of age. At this point, they transition from playful puppies to graceful adults, exhibiting all the characteristics and traits of the breed.

As puppies, Cavaliers experience rapid growth and development. During this time, it is crucial to provide them with a well-balanced diet and regular exercise to support their healthy growth.
