Will it hurt a dog to give them two doses of flea medicine?

Giving a dog two doses of flea medicine can be dangerous and may cause serious health problems. Most flea and tick medications are designed to be given at specific intervals, usually once a month. Overdosing on flea medicine can lead to a number of side effects, including:

- Vomiting

- Diarrhea

- Lethargy

- Seizures

- Liver damage

- Kidney failure

In some cases, an overdose of flea medicine can even be fatal. If you think your dog may have received too much flea medicine, contact your veterinarian immediately.

It is important to follow the dosing instructions on the flea medicine package carefully and to only give your dog the recommended dose. If you have any questions about how much flea medicine to give your dog, talk to your veterinarian.
