Animal Health

Bayer is committed to ensuring that the relationship between animals and humans remains positive, to protect animals and benefit people. As one of the world’s largest suppliers of veterinary medicinal products, we offer pet owners, veterinarians and farmers a wide range of animal health products for use in household pets, horses and livestock.

The role animals play in our lives is growing in significance, and as humans and animals live closer together, it has also become more necessary to protect humans from the transmission of disease pathogens. Bayer has secured a leadership position in researching and developing products for animal health and pest control since 1919, and we are constantly developing new products and improved forms of administration for the benefit of the animals in our lives.
Our product range has been developed through Bayer's own research and development programmes, specialising in infectious disease and parasite protection for animals.


Products include:

• Comprehensive parasite treatments for companion animals, available in tablet, spot-on and collar formulations

• Innovative products that repel ticks before they can bite, reducing the risk of diseases which they may transmit

• A ground-breaking antimicrobial product used to treat bacterial diseases in dogs, cats and exotic animals (small mammals, reptiles and birds), as well as cattle, pigs and certain classes of poultry.


Please note that all product information on this website relates only to non-prescription products with marketing authorisations in the UK and Ireland. We also offer a range of prescription products available through the veterinary channel. For more information about these products, please contact your vet.
