1. "Sour" can mean different things:
* Slightly sour smell: This could be normal, especially for wet food that's been open for a while. It's usually okay if the food smells slightly sour, as long as it hasn't gone bad.
* Strong sour/rotten smell: This indicates spoilage and should be discarded immediately.
2. The type of food matters:
* Dry food: Dry food has a longer shelf life, and a slight sour smell might be acceptable for a short period.
* Wet food: Wet food has a shorter shelf life, and it's more likely to spoil quickly.
3. Puppies are more susceptible:
Puppies have delicate digestive systems and are more likely to get sick from spoiled food.
Here's what you should do:
1. Inspect the food: Look for any signs of mold, discoloration, or a strong sour smell.
2. Check the expiration date: If the food is past its expiration date, it's best to discard it.
3. Smell the food: A slight sour smell might be acceptable, but a strong sour or rotten smell means the food is spoiled.
4. Trust your instincts: If you're unsure, it's always best to err on the side of caution and discard the food.
If you are concerned your puppy has eaten spoiled food, contact your veterinarian immediately. They can advise you on the best course of action.
Remember, feeding your puppy fresh, high-quality food is essential for their health and well-being.
