1. **Weight Loss**: Despite a normal or increased appetite, dogs with parasites often lose weight. This can be due to the parasites stealing nutrients from the dog's food.
2. **Vomiting**: Frequent vomiting or the presence of worms in the vomit can indicate a parasitic infection. For example, roundworms can sometimes be seen in vomit.
3. **Diarrhea**: Persistent diarrhea, especially if it is bloody or contains mucus, can be a sign of parasites like giardia or whipworms.
4. **Itching and Scratching**: Fleas, mites, and ticks can cause excessive itching and scratching, leading to skin irritations or infections.
5. **Bloated Stomach**: A distended or bloated abdomen can be a sign of certain parasites, especially in puppies.
6. **Lethargy**: If your dog seems unusually tired, weak, or less active than usual, it could be a sign of a parasitic infection.
7. **Changes in Appetite**: Some dogs may show an increased appetite, while others may refuse food altogether.
8. **Flea Dirt**: If you notice small black specks (flea dirt) in your dog's fur or on their skin, this indicates a flea infestation.
9. **Coughing**: Certain parasites, like heartworms, can cause coughing or other respiratory issues.
If you notice any of these symptoms in your dog, it’s essential to consult your veterinarian for a proper diagnosis and treatment plan. Regular veterinary check-ups and preventive medications can help keep your dog free from parasites.
