What Does “Not Eating” and “Not Drinking” Mean?

Not Eating: When a dog refuses food, whether it’s dry kibble, wet food, or treats. This can be a sign of loss of appetite, stress, illness, or dental problems.

• Part of speech: Verb phrase
• Examples:

1. My dog is not eating her breakfast today.
2. He has been not eating for two days.
3. Some dogs are picky and occasionally not eating a new brand of food.

Not Drinking: When a dog refuses water, milk, or other fluids. This can be a serious warning because dehydration sets in quickly.

• Part of speech: Verb phrase
• Examples:

1. My dog is not drinking water since morning.
2. He became weak because he was not drinking enough.
3. Sometimes dogs are nervous in a new environment and not drinking immediately.

Mini Story: Imagine your dog as a small engine. Food fuels the engine, water keeps it running smoothly. Without either, your dog can slow down or get sick.

Common Mistakes and How to Avoid Them

Pet owners sometimes confuse minor picky eating with serious illness, or they overlook dehydration signs.

Incorrect:

1. I assume my dog is fine because he skips one meal.
2. I don’t worry when he refuses water for a few hours.
3. I give only dry food thinking it’s enough hydration.

Corrected:

1. Monitor food intake and consult a vet if missing more than 24 hours.
2. Ensure your dog drinks water; offer wet food or ice cubes.
3. Provide fluids separately; hydration is critical.

Why mistakes happen: Owners often underestimate the speed at which dogs can become dehydrated or weak. Early observation is key.
