postage high for 1 item the shop price is cheaper due to high postage costs


good service and useful product


seem to be working just fine. my dog has bouts of anxiety and is much calmer now


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.




This product was the answer to a prayer. Twelve year old dog with one year of urinary night time accidents and infections was calmed by this product. Now is dry and relaxed!!


I recently tried a cheaper brand of calming tablets for my dog but have now returned to Serene-um. As with most things - you get what you pay for. Very pleased with the product.
