If a dog has terminal cancer can another sense this and would the other attack sick because of his condition?

Dogs are incredibly intuitive and sensitive creatures, but they don't have the same understanding of disease and death as humans. While a dog might notice changes in a sick companion's behavior or physical appearance, they wouldn't understand that the illness is terminal or a threat.

Here's why your dog wouldn't attack a sick companion:

* Lack of Understanding: Dogs don't grasp the concept of death or illness in the way humans do. They react based on instinct and immediate cues.

* Social Cues: Dogs primarily rely on social cues like body language and scent to understand each other. A sick dog might exhibit different behaviors (less playful, weaker, etc.) but wouldn't necessarily trigger an aggressive response.

* Pack Behavior: Even in pack animals, aggression is usually reserved for defending territory or resources. A sick dog wouldn't be perceived as a threat in the same way.

What to expect:

* Changes in Interaction: Your healthy dog might notice changes in the sick dog's behavior and interact with them differently, such as being more gentle or less playful.

* Increased Affection: Sometimes, a healthy dog might become more affectionate with a sick companion, possibly sensing their vulnerability.

Important note: While dogs wouldn't attack a sick companion due to their illness, it's crucial to monitor interactions between your dogs if one is sick. You might need to adjust their environment to ensure a peaceful coexistence and make sure the sick dog feels safe and comfortable.

If you're concerned about your dog's behavior or health, consult with your veterinarian. They can provide expert advice and support during this difficult time.
