Zylkene Plus for Large Dogs is a calming complementary feed product which combines two natural origin ingredients to offer a gentle, yet reliably effective way to help pets manage prolonged or recurring emotionally challenging situations.

Zylkene Plus combines the natural origin active ingredients alpha-casozepine and white fish muscle hydrolysate. The effect of alpha-casozepine is based on the principle of satiety and sleepiness in new-borns after feeding on milk/colostrum. Hydrolysing white fish muscle yields bioactive peptides and amino acids that are considered to have calming properties.*

The formulation makes it easy to support the long-term emotional wellbeing of every pet:
Suitable for use in dogs and cats of all breeds and sizes, and is effective both inside and outside the home
Capsule formulation that can be sprinkled on food, for easy administration
