Review: Works great. - Basic personal hygiene/cosmetic for your bathroom. Good value for the price. Is as advertised. Keep on hand.
Review: A wonderful inexpensive option! - Our dog has environmental allergies that get a little rough in the spring and summer. He gets itchy and will scratch and get red splotches. We worked with our vet to change out his food and put him on some supplements and oil which help a LOT. A very popular RX was not an option after he had some bad side effects. And my vet didn’t think his symptoms were bad enough to keep him on something like that anyway! The vet suggested getting some diphenhydramine instead and giving it to him during the time when it seems to be the worst, and when we go on our vacations and take him to the woods, etc. he is 75 lbs and he gets one in the morning and one in the evening per our vets instructions. I was very pleased to find a bottle this size for this price! It’s wonderful especially with how expensive his other foods and supplements are! The quality is there and they are easy to hide in cheese or a pill pocket! Highly recommend if you vet makes this suggestion! Only with their recommendation!
