Section 05
Care, Cost and Maintenance
Correct Dosing
Always weigh your dog before dosing. Use the weight-based chart on the package. Overdosing can cause toxicity; underdosing may not clear the infection.
Timing & Repeat Treatment
Most dewormers require a second dose 2-4 weeks later to kill newly hatched worms. Follow the product’s schedule for full elimination.
Sanitation & Prevention
Pick up feces promptly, wash bedding, and treat your yard. Monthly heartworm preventives often also control roundworms and hookworms.
Pro tip
Give dewormer with a small meal to reduce risk of vomiting. If your dog spits out a partial tablet, do not re-dose without consulting your vet, you may need a fresh dose.
Frequently asked questions
How often should I deworm my small dog?
For puppies, deworm every 2 weeks until 12 weeks of age, then monthly until 6 months. Adult dogs should be dewormed at least every 3 months, or more often if they hunt or scavenge.
Can I use a dewormer meant for large dogs?
No. Large dog dewormers contain higher doses that can be toxic to small dogs. Always choose a product formulated for your dog’s weight range.
What are signs my dog has worms?
Look for visible worms in stool or vomit, scooting, weight loss, bloated belly, poor coat, or diarrhea. Some dogs show no symptoms, so regular fecal checks are important.
Are these dewormers safe for puppies?
Most products are safe for puppies 2 weeks or older, but always check the label. Some dewormers require a minimum age or weight. When in doubt, consult your vet.
What if my dog vomits after taking dewormer?
Mild vomiting can occur. If it happens within 30 minutes, the dose may not be absorbed; consult your vet about re-dosing. If vomiting persists, stop use and contact your vet.
