Not so much for my Rottie
I have a female rottweiler that has become terrified of rain, thunder and I've tried a Thunder Shirt, I've tried a pheromone spray (Adaptil) & now Zylkene 450 mg, twice a day (she weighs 87 lbs). All they have done is to take the edge off, only slightly. Was really hoping it would work.
