    "My elderly Siberian Husky has dementia and becomes anxious at any change in her routine. She can also be hyperactive and restless. I usually give her one Serene-UM in the evening so she settles during the night. If there's going to be a change in routine i.e. visit to the Vet or Groomer (stressful anyway) I give one Serene-UM an hour and a half beforehand. I've found the medication does what it's says and I'll certainly keep on using it."
