If you notice any of these side effects in your dog after applying flea and tick drops, it is important to contact a veterinarian immediately.

Here are some tips for avoiding diarrhea in your dog after applying flea and tick drops:

Do not apply the drops to your dog's skin directly. Instead, apply them to a spot on your dog's coat that they cannot reach, such as the back of the neck.

Follow the directions on the product label carefully. Do not apply more than the recommended amount of drops.

Do not allow your dog to lick the area where the drops were applied.

If your dog is sensitive to flea and tick drops, talk to your veterinarian about other options for preventing fleas and ticks.
