Yes, ticks can be harmful to dogs. These small parasites can attach themselves to your dog’s skin and feed on their blood, which can lead to several health issues. Ticks can transmit various diseases, including Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis. Symptoms of tick-borne diseases can vary but may include fever, lethargy, loss of appetite, joint pain, and swelling.

To protect your dog from ticks, consider the following tips:
1. **Preventative Treatments**: Use veterinarian-recommended tick prevention products such as topical treatments, collars, or oral medications. These can help repel and kill ticks before they attach.
2. **Regular Check-ups**: After walks or outdoor activities, inspect your dog thoroughly for ticks, especially in areas like the ears, between toes, and under the collar.
3. **Maintain a Clean Yard**: Keep your yard tidy by mowing the lawn regularly and removing any tall grasses or brush where ticks might thrive.
4. **Avoid Tick Habitats**: Try to avoid letting your dog roam in areas known for high tick populations, such as dense woods or tall grass, especially during peak tick season.
5. **Vaccinations**: Consult with your veterinarian about vaccines that can help prevent tick-borne diseases.

If you find a tick on your dog, remove it carefully using tweezers, grasping the tick as close to the skin as possible, and pulling upward with steady pressure. After removal, clean the area with antiseptic and monitor your dog for any signs of illness. If you notice any unusual symptoms, contact your veterinarian immediately.
