Age is More Than Just a Number:

Think about it – a little puppy isn’t going to have the same biting power as a full-grown adult Newfoundland. The prime biting years are usually between 3 to 7, and as they gracefully step into their senior years, their strength might take a bit of a dip. It’s just a natural part of the aging process.

Genetics and Anatomy Unraveled:

Now, let’s dive into the science of it all. Genetics and anatomy play a big role – it’s like their unique blueprint. From jaw muscles to joints, teeth, and more, it’s a complex system. The jaw adductor muscles, including the temporal, masseter, medial, and pterygoid muscles, are the key players here. They’re the muscles responsible for eating and chewing, and the temporomandibular joint (TMJ) is their go-to joint. The size and power of these muscles and joints are influenced by the dog’s inherited genetics. So, you can have quite a variety from one Newfie to another – it’s like their own unique fingerprint. Some may even face challenges like muscle injuries or diseases that weaken them over time.
