Frequently Asked Questions (FAQs)

1. Do flea collars for dogs actually work?

Yes, flea collars for dogs are generally effective and provide lasting protection for several months. However, it's important to monitor your dog for any localized skin reactions or allergies. Larger dogs may require additional protection to cover their entire body.

2. What are the negatives of flea collars?

Flea collars can have several negative side effects, including vomiting, seizures, muscle spasms, organ failure, skin problems, and behavioral issues. The chemicals used in the collars can be toxic to pets and may cause chemical burns and hair loss around the neck area.

3. Why do vets not like flea collars?

Vets may have concerns about flea collars because ingestion of the collar or absorption of the chemicals into the body can be toxic to dogs. Some dogs may be particularly sensitive to certain chemicals used in flea collars.

4. Do flea collars work if they already have fleas?

Yes, flea collars are designed to kill fleas. Some collars specifically target adult fleas, while others may also kill younger stages of fleas. They can be effective in treating existing flea infestations on dogs.

5. How long should I leave a flea collar on my dog?

Under normal conditions, it is recommended to replace the flea collar every seven months for continuous protection. However, if your pet is exposed to severe flea and tick infestations, it may be necessary to replace the collar more frequently. It is important not to replace the collar any earlier than five months.
