Do Flea Collars Really Work on Dogs?

Flea collars are an effective method to control fleas and prevent infestations. While some collars only kill adult fleas, others can prevent future infestations by killing larvae. You should always look for a collar that kills more than one life stage. By killing the larvae, it breaks the flea life cycle.

Flea collars are especially beneficial for areas with high humidity and densely wooded areas. The collars release the medication over a period of months, making them less messy than topical treatments. Nonetheless, they are not foolproof and should only be used as supplemental treatment options.

In addition to killing fleas, these collars can also cause adverse effects on your dog. Many of them contain chemicals that can cause skin reactions and rashes. Therefore, you should always test them on your cat or dog and remove them if you notice any rashes or skin irritation. It’s a good idea to wear gloves when handling chemicals and always wash your hands thoroughly afterward.

When applied to your dog’s neck, flea collars are effective against adult fleas and larvae. If you have any doubts, consult your vet immediately. If you notice a flea on your dog after applying a collar, you should remove it and wash the area with water.
