Can you use frontline for cats on a dog?

No, you should not use Frontline for cats on a dog.

Frontline is a brand of flea and tick medication that is formulated specifically for cats and dogs. While the active ingredients are similar, the concentrations and formulations are different.

Using Frontline for cats on a dog can lead to:

* Toxicity: The higher concentration of active ingredients in cat-specific Frontline can be toxic to dogs, potentially causing skin irritation, neurological issues, and even death.

* Ineffectiveness: The formulation for cats may not be as effective in repelling or killing fleas and ticks on dogs.

It is crucial to always use a veterinarian-approved flea and tick medication that is specifically designed for your dog's breed, age, and weight. Your veterinarian can advise you on the best options for your pet.

Always follow the instructions on the product label carefully.

If you suspect your dog has ingested Frontline for cats, contact your veterinarian or the ASPCA Animal Poison Control Center immediately.
