Common questions
How much should a Greater Swiss Mountain Dog weigh at 3 months old?
At around 12 weeks (3 months), a Greater Swiss Mountain Dog puppy typically weighs about a third of their eventual adult weight - roughly 14.9–21.1 kg for males and 11.9–16.5 kg for females, based on this breed's adult weight range of 45–64 kg (male) and 36–50 kg (female).
When does a Greater Swiss Mountain Dog stop growing?
Most Greater Swiss Mountain Dogs reach close to their full adult weight by around 12 months old, though large breeds can continue filling out in muscle and chest depth for several months after that. Larger breeds generally take longer to fully mature than smaller ones.
My Greater Swiss Mountain Dog puppy seems small/large for their age, should I worry?
Individual puppies vary, and these figures are typical ranges, not strict rules - genetics, litter size, and nutrition all play a part. If your puppy is well outside these ranges, gaining or losing weight rapidly, or you're generally concerned, check with your vet rather than relying on any online chart alone.
