Here's why:
* Different dosages: The active ingredients in dog and cat wormers are often the same, but the dosages are different. Giving a dog a cat wormer could lead to an overdose, causing serious health problems or even death.
* Different formulations: Even if the active ingredient is the same, the formulations of dog and cat wormers can be different, making them unsuitable for the other species.
* Different metabolic rates: Cats and dogs metabolize medications differently, meaning a dose that's safe for one species may be toxic to the other.
If you are concerned about your pet's health, please consult with a veterinarian immediately. They can provide you with the correct medication and dosage for your pet.
