7 FAQs About Flea and Tick Collars for Dogs

Flea and tick collars can provide an easy way to protect your dogs from fleas and ticks. However, sometimes the question of how effective flea and tick collars are arises. Below we have listed a detailed breakdown of everything one needs to know about flea and tick collars. The guide below will answer all your questions to make an informed decision.


1. How do Flea Collars Work in Dogs?


The main intent of a flea collar is to either keep the parasites away for good or even kill them. Depending on the kind of collar you choose, it will perform either of the two functions.


The original or more traditional flea collar works by releasing toxins around the collar that kill all the fleas. However, modern flea collars work a little differently. They use repellents to keep the fleas away instead of toxins to kill them. This advanced chemical is let out into the fur and skin of your pet through natural oils and creates a protective layer on their body. This created layer actively works to keep all the fleas and ticks away, keeping your dog safe.


As compared to the traditional collars that used poisonous substances like organophosphates or permethrin, the modern-day collars are more efficient and safe. The traditional collars were risky for homes with felines or children.


Hence, you should find a flea collar that provides comfort to your dog. Keeping in mind your family and the breed of dog you have, your vet should be able to recommend the perfect flea collar for your dog, which will be safe for you and your dog.

This is why one should always use a doctor-recommended flea collar.


This brings us to the question, are flea collars safe for dogs? Yes, flea collars used with proper care and recommended by doctors are safe for your dogs.

Always keep your dog in sight and check whether the chemicals are being rubbed into home surfaces through the collar. You should be even more discreet if you have children around.

Washing hands before eating (especially if you have touched the collar) is also crucial. This should keep you and your family safe.


5. Can My Dog Swim with a Flea Collar On?


If you have a dog who loves water, it is wise to read the instructions on the label. Flea collars are mostly water resistant but not waterproof. Constant contact with water might spoil it.


Since it releases chemicals into the dog's fur, it can also be harmful to water animals. Hence, it is mostly advised to take off your dog’s collar when it comes in contact with water. Keep it off whether your dog is taking a bath, going for a swim or even splashing around in the rain. The environment, your dog and you should always be safe. It is best not to compromise the longevity and effectiveness of the collar, so use it wisely.


6. How Tight Should a Flea Collar Fit?


A two-finger gap is an ideal fit for the flea collar. As its job is to protect from and kill fleas, it needs to maintain skin-to-skin contact at all times but not be so tight that it may cause irritation in the neck or cause it to choke. Do not keep the width too long as the dog might tend to chew which might break parts of the collar off which in turn is dangerous for children. Children should not be touching or playing with the collar as it may be harmful to them.


Always keep checking the tightness of the collar to have the best effect without compromising anyone’s safety. It is important that your dog is comfortable with the collar they are wearing as they might be prone to chewing it or trying to take it off.


7. How often should I replace my dog's flea collar?


Expensive collars can last for around 8 months, but most collars tend to lose their usability within a few months. The more the collar gets wet the more its usefulness reduces. Hence, one should actively change the flea collar every few months to keep the parasites like fleas, ticks and lice away.


It is advisable to change the flea collar as per the instructions on the label to keep your dog safe from the bugs. One can also maintain the calendar to point out exactly when the efficiency of the collar reduces and then replace it, for best results.
