Your dog may freak out after the application of flea medicine. The possible reasons behind this weird behavior of your dog after flea medication can be many.

Dogs that freak out after applying flea medication can hurt themselves somewhere. Not only this, but some owners have observed that their dog has suddenly started getting reactions from their usual flea medications, which leads to weird behavior in dogs. If you have a lazy dog, the application of flea medications can make the situation worse.

The reason for the weird behavior of your dog after flea medication application can be physical or psychological. The best rational decision is to consult your dog’s veterinarian whenever you notice your dog behaving weirdly after applying or consuming flea medication.

Here are some possible reasons that may cause your dog to behave weirdly after applying flea medication.

1. Allergies

Your dog may be allergic to anything. You will not know about your dog’s allergy unless and until your dog comes across any allergens that show weird effects or reactions on your dog’s body. Your dog can be allergic to any allergen, and it can be present in your dog’s food, medications, environment, etc. Dogs can be allergic to even the anti-allergy medications you give them. So don’t forget to consult a veterinarian before giving any medications to your dog, even anti-allergic medications.

Flea medications may contain an allergen that triggers an allergic reaction, resulting in your dog’s weird behavior.

2. The wrong flea treatment

Dog owners should always be careful while providing flea medications to their dogs. One of the most common reasons a dog starts behaving weirdly after flea medications is the unjust treatment provided to stop flea infestation in dogs.

Every dog has flea treatment requirements according to the dog’s body and the breed to which your dog belongs. Say, if you give your large dog the flea medication you used for your small dog, it will cause problems and vice versa. Remember that the dog’s veterinarian should prescribe the flea medications you give to your dog.

The flea medications you give to your dog should be after completely calculating your dog’s age, height, weight, size, and other factors. If you give your dog the wrong flea treatment, it can cause many problems, including the dog’s weird behavior. Thus, always be careful and don’t forget to consult your dog’s vet.

3. Wounds

If your dog has any wounds on its body, be careful while providing flea medications, especially while applying flea medications. Sometimes, due to wounds on your dog’s body, the toxic medications can enter the dog’s skin and then spread throughout the dog’s body.

If the wound in your dog’s body is deep, there are high chances that the flea medication will travel deep into your dog’s bloodstream and cause toxicity. Thus, consulting a veterinarian about the issue of wounds before the application of flea medications is extremely necessary.

4. Ingestion

Put the flea medication on your dog’s body so that your dog cannot lick it. If you put it on your dog’s body in such an area that your dog can easily lick it, it will cause trouble. The dog can easily ingest this medication after licking the area where you spray the medication, so the trouble that follows afterward will be harmful.

Dogs are often interested in chewing on different things. If you have put flea medication near the dog’s collar, your dog may lick it. Ingestion of flea medications is toxic, leading to some serious health issues in your dog afterward. Your dog is acting weirdly suddenly after a flea medication application has this ingestion as one of the main reasons.

There are various ectoparasites you can use on your dog’s body to prevent fleas. These ectoparasites are of different kinds depending upon their different brands. For example, here is a list of different ectoparasiticides in different flea medications or dog hygiene products like shampoos.

  • Organophosphates: Organophosphates are highly toxic. Organophosphates make their use in flea collars but not in pipettes.
  • Pyrethrins: Pyrethrins make their use in organic compounds. Pyrethrins can be obtained from a plant, namely the chrysanthemum. Various insecticides include pyrethrins. They are mainly used to kill insects like mosquitoes and fleas on animals such as dogs.
  • Indoxacarb: Indoxacarb is the main pesticide used for killing fleas in animals, mainly dogs and cats. Indoxacarb is not very toxic for dogs but highly toxic for cats.
