Too Much Flea Medicine on Dogs Symptoms 

If your pup loves to play outside, then you’ve most likely treated them with flea and tick medicine. Fleas and ticks are most active during the spring and summer, typically the time when your dog will spend the most time outside. Flea medications are an effective way to keep your dog safe from these parasites, but is there such a thing as too much flea medicine? If you’re overtreating your dog, they can experience adverse effects. 

Misuse of Flea Medicine 

If you are using flea medicine correctly, your pet should have no issues. When severe effects from flea medications occur, it’s often due to incorrect treatment. If the medication is applied excessively or if your pup ingests it, the toxins can affect their nervous system and cause a range of problems. Other examples of misuse include applying cat flea medicine on your dog, which results in adverse reactions. A common occurrence is that many owners mistake the medication working as having a negative reaction to the treatment. Your dog may experience slight discomfort or itching at the application site, but this will go away on its own and it’s not a cause for concern. After every use, properly secure the product away so your dog cannot ingest the medication.
