Here are two facts about dogs:

1. Dogs can understand up to 250 words and gestures. They can learn to recognize their names, commands, and even specific objects. This ability makes them incredibly trainable and responsive companions.

2. Dogs have a "sixth sense" that allows them to detect changes in a person's mood or health. They can sense stress, anxiety, and even impending seizures in their owners. This sensitivity makes them valuable companions for people with health issues.
