When Should A Male Great Dane Be Neutered?

Neutering of a male Great Dane is the surgical removal of their testes. It is an important procedure that presents many benefits to a Great Dane.

So, when should a male Great Dane be neutered? A male Great Dane should be neutered when they are at least 12 months old or 1 year old, after reaching puberty. Neutering at this age allows time for the development of hormones that are essential for muscle development as they grow into adults.

Neutering earlier than 12 months of age interferes with this important developmental stage which can result in an inability to gain the normal muscle mass throughout their life.

A neutered Great Dane also presents less aggressive behavior, territorial marking as well as production of unwanted puppy litters when they find a female partner.

In this post, you will learn all about the neutering of male Great Danes, the pros and cons, the effect of the procedure on their growth, behavior, and recovery time. 

Does neutering a Great Dane stunt growth?


Neutering a Great Dane does not stunt their growth, however, it might affect their joints when they are neutered at an early age before the age of 1 year.

Studies have shown that large breed dogs such as the Great Dane that are neutered before reaching one year of age may experience delayed closing of the growth plate which causes them to grow taller than normal and develop joint disorders because of their heavyweight.

The joint disorders they develop include elbow dysplasia, hip dysplasia, and cranial cruciate ligament tears in the knees leading to hind-limb lameness.

Traditional Great Dane neutering ages have been between 6 and 9 months but because of scientific research evidence, neutering policies have been reviewed.

It is also always important to talk to your vet regarding neutering a Great Dane and follow their guidance on it.
