Choosing between Sentinel and Heartgard for your dog's heartworm prevention can seem confusing, but understanding the differences can help you make an informed decision.
- Sentinel protects against heartworms, fleas, and several intestinal parasites.
- Heartgard is primarily aimed at preventing heartworms but also treats and controls some intestinal worms.
- Both medications are usually administered monthly and require a prescription from your veterinarian.
When selecting a heartworm preventive, it's crucial to consider your dog's overall health needs, lifestyle, and any specific concerns you might have. Sentinel offers broader protection, which can be advantageous if your pet has exposure risks beyond heartworms. Heartgard focuses on heartworm prevention, which might be more suitable if your dog is at lower risk for other parasites.
