Before You Buy
Key Buying Factors
01
Active Ingredients
Look for FDA-approved ingredients like praziquantel, pyrantel pamoate, and fenbendazole. These target specific worms; combination formulas cover multiple types.
02
Worm Spectrum
Choose a dewormer that covers tapeworms, roundworms, hookworms, and whipworms if needed. Small dogs often encounter tapeworms from fleas.
03
Dosage Accuracy
Small breeds need precise dosing. Liquid or chewable formats allow for weight-based dosing, reducing the risk of under- or overdosing.
04
Safety for Small Dogs
Verify the product is labeled for puppies and small breeds. Avoid ingredients harmful to young dogs, like certain organophosphates.
05
Ease of Administration
Tablets can be hidden in food; liquids can be mixed or given directly. Palatable options ensure your dog takes the full dose.
06
Price per Dose
While our guide is current pricing compare cost per treatment. Multi-dose packs offer better value for ongoing prevention.
Living With It
Care, Cost and Maintenance
Deworming Schedule
Puppies should be dewormed every 2 weeks until 12 weeks of age, then monthly until 6 months. Adult dogs need treatment every 3-6 months based on risk.
Dosage Precision
Always weigh your dog before dosing. Split tablets accurately or use liquid formats with a syringe for small breeds.
Monitor for Side Effects
Watch for vomiting, diarrhea, or lethargy. Most side effects are mild and resolve within 24 hours. Consult your vet if symptoms persist.
Pro tip
Always confirm the product is labeled for your dog’s exact weight. For small breeds, we prefer liquid or breakable tablets to avoid underdosing.
Frequently asked questions
How do I know which dewormer to choose for my small dog?
Check the product label for your dog's weight range and target worms. If your dog has fleas, choose one that treats tapeworms. For general prevention, a broad-spectrum option like PetArmor 7-Way is our team's top recommendation.
Can I use a large dog dewormer on a small dog?
No, large dog dewormers may contain too high a dose. Always use a product formulated for your dog's weight to avoid toxicity.
How often should I deworm my small dog?
Puppies need more frequent deworming (every 2 weeks until 12 weeks). Adult dogs on prevention should be treated every 3-6 months, or as recommended by your vet based on exposure risk.
Are over-the-counter dewormers safe for puppies?
Many are safe when used according to the label. Look for products specifically labeled for puppies and follow age/weight guidelines. We prefer liquids for young puppies for accurate dosing.
What if my dog vomits after taking the dewormer?
Mild vomiting can occur. If it happens within 30 minutes, you can re-dose once. If vomiting persists or your dog seems unwell, contact your veterinarian.
