Parasite control can keep pets healthy for longer. 

Parasites such as fleas, ticks, roundworms, and tapeworms can cause problems for dogs and cats – parasites can cause irritation and carry diseases – unless they receive routine preventative treatments. Keeping parasitic pests away is essential to keeping your pets healthy.  

Below is a brief overview of our parasiticide products:


BRAVECTO is indicated for the treatment of tick and flea infestations on dogs and cats and can also be used to treat mites. BRAVECTO effectively kills fleas and multiple tick species for up to 12 weeks with a single dose. BRAVECTO comes in various formulations including chewable tablets and spot-on treatments. 


Collar to protect dogs from multiple parasites, including ticks, mosquitos and sand flies. Many of these parasites can transmit serious diseases, such as Leishmaniosis and Lyme disease, underscoring the need to protect our pets.

Protection from disease is a goal we all share. 

Vaccination can help to protect your pets from many diseases, such as parvovirus, distemper, leptospirosis, and kennel cough. Routine vaccination is an important aspect of animal healthcare to ensure the health and well-being of our pets. Our NOBIVAC® portfolio of products contains an extensive range of vaccines that protect dogs, cats, and rabbits against many different diseases.  


Merck Animal Health is committed to helping your diabetic pet live a happy, healthy life. 

Diabetes mellitus leads to higher-than-normal amounts of glucose, or sugar, in your pet’s blood. This condition occurs when your pet’s body makes too little or no insulin. Proper care can help your diabetic pet live a happy, healthy life – which includes a daily routine of insulin treatment, diet and exercise.  

Below is a brief overview of some of our key diabetes therapeutics: 


Insulin for the treatment of diabetes mellitus in dogs and cats. Vetsulin may be administered using U-40 syringes or via VetPen®, the first injection pen device designed for use in dogs and cats with diabetes.
