Why do Newfoundlands drool?

1. Breed Characteristics: Newfoundlands have a naturally loose jowls and large muzzles, which contribute to their drooling. The shape of their mouths and the folds of skin around them make it difficult for them to keep saliva contained.

2. Anatomic Features: The Newfoundland breed has a large lower lip and a deep lower jaw. These features can obstruct the complete closure of the mouth, which leads to saliva seeping out.

3. Excessive Thirst: Newfoundlands may drool excessively due to a medical condition called polydipsia, which causes them to drink excessive amounts of water. This increased water intake can lead to increased salivation and drooling.

4. Excitement and Heat: Newfoundlands often drool when they are excited, happy, or panting due to heat or exercise. When panting the mouth is open and saliva may drip.

5. Relaxation: Newfoundlands may also drool when they are relaxed or sleeping, as the muscles around their mouths may become more relaxed and allow saliva to escape.

It's important to note that drooling is a natural occurrence for Newfoundlands and is not usually a cause for concern unless it is excessive or accompanied by other symptoms.
