I was skeptical after research showed only 50% of dogs were helped by zylkene, but it has been effective for one of my dogs, so 50% effective seems correct! My dog has been less stressed and growly when he's tired and when my other dog growls at him.

Can I ask would these be okay for a dog who has a milk allergy

  • VioVet Staff

Hi there,

As Zylkene® is a milk-derived nutritional supplement, we would not recommend feeding it to a dog with a milk allergy.

Thank you for your question.

Zylkene does not have any chicken or beef in it, it is an ingredient derived from a milk protein.

Hope that helps,
