Can a dog die from flea collar?

In some cases, yes, a dog can die from a flea collar. Flea collars work by releasing pesticides into the dog's fur and skin. These pesticides can cause a variety of side effects, including skin irritation, respiratory problems, and neurological damage. In severe cases, these side effects can lead to death.

Dogs that wear flea collars that contain propoxur or pyrethroids, both of which are insecticides that can be absorbed through the skin or inhaled, are at risk of these side effects. Symptoms can include weakness or muscle tremors, seizures, vomiting, difficulty breathing, or panting without exercise.

If you are concerned that your dog may be having a reaction to a flea collar, remove the collar immediately and bathe your dog with soap and water. You should also contact your veterinarian for further instructions.

There are a number of other ways to protect your dog from fleas and ticks without using a flea collar. These include using topical flea and tick medications, oral flea and tick medications, and flea and tick shampoos.
