Is Nexgard Spectra Safe For Border Collies


Border Collies are intelligent and energetic dogs that require proper care and attention. One aspect of their health that dog owners need to consider is flea and tick prevention. Nexgard Spectra is a popular product in the market, but is it safe for Border Collies? Let’s examine its safety profile and understand whether it is suitable for this particular breed.

Understanding Nexgard Spectra

Nexgard Spectra is a chewable tablet that combines two active ingredients: afoxolaner and milbemycin oxime. Afoxolaner is effective against fleas and ticks, while milbemycin oxime provides protection against intestinal worms and heartworm disease. The combination of these two ingredients makes Nexgard Spectra a broad-spectrum parasite control product.

Border Collie Sensitivity

Border Collies, like any other breed, can have individual sensitivities to certain medications. While Nexgard Spectra is generally safe for most dogs, it is crucial to consider your Border Collie’s specific health condition and any known sensitivities before administering any medication. Consulting with your veterinarian is always recommended to ensure the safety of your pet.

Potential Side Effects

Like any medication, Nexgard Spectra may have potential side effects. Some common side effects reported in dogs include vomiting, diarrhea, lethargy, and loss of appetite. These side effects are generally mild and temporary. However, if you notice any unusual symptoms or your Border Collie experiences severe reactions, contact your veterinarian immediately.

Alternative Options

If you are concerned about using Nexgard Spectra for your Border Collie, there are alternative options available. Your veterinarian can recommend other flea and tick prevention products that might be better suited for your dog’s specific needs. Always discuss any concerns or preferences you have with your vet to find the most suitable solution.

Tips for Safe Usage

To ensure the safety of your Border Collie when using Nexgard Spectra or any other medication, follow these tips:

  • Administer the correct dosage based on your dog’s weight.
  • Read the product label and follow the instructions carefully.
  • Monitor your dog for any adverse reactions after administration.
  • Keep the medication out of reach of children and other pets.
  • If you have multiple pets, prevent them from licking each other immediately after administration.


Nexgard Spectra can be a safe and effective option for flea and tick control in Border Collies. However, it is crucial to consider your dog’s individual sensitivities and consult with your veterinarian before starting any medication. By following the recommended dosage and monitoring your pet for any adverse reactions, you can help ensure the well-being and safety of your beloved Border Collie.
