At Vetoquinol, we’re experts in companion animal behaviour. And our supplements help companion animals stay calm in unexpected situations.

Although pets can’t tell their owners how they feel, their behaviour speaks volumes. A dog that loses its playfulness or a cat that relieves itself indoors are clearly not feeling well. 

Owners can help their pets adapt to change with Zylkene®. This is a natural and patented dietary supplement derived from milk protein. It contains a unique blend of alpha-casozepine, vitamins, minerals and nutrients which help to relax stressed pets.
