Why has your vet prescribed Zenrelia for your dog?
Following your vet consultation, your vet has prescribed a medicine called Zenrelia to help relieve your dog’s itchy skin. Your vet may have explained that there are four common forms of allergic itch in dogs:1,2
Canine Atopic Dermatitis (CAD) - caused by environmental allergens, such as pollen or house dust mites. This is the most common type of skin allergy in dogs.
Parasite allergies - such as to flea bites
Food allergies - often to protein sources such as beef, dairy, chicken or pork in your dog’s diet, treats or medications. You dog may also have digestive as well as itch symptoms.
Contact allergies – triggered by direct contact with substances, for example plants, cleaning products or certain materials.

Giving your dog Zenrelia
The tablets are hypoallergenic and free of flavour additives that could trigger food allergies.4
The tablets have a dividing line so can be split in half for doses involving half a tablet.
Zenrelia can be given with commonly used medications such as vaccines, antibiotics, parasite treatments and NSAIDs (non-steroidal anti-inflammatory drugs used to reduce pain and inflammation) but always follow the advice from your vet before doing so.4
If you have any questions about Zenrelia, please speak to your vet.
