This is a money factory, really hustle you in, charge a fortune and give the dog an off the shelf treatment. Dr. Trimmer recommended a dose of 40 mg of Claritin per day, this is 4 x the human dose. Dr. Trimer said that dogs process medications much quicker than humans and it was therefore 100 safe. My dog's hair fell out and he got bad dandruff. Within one day of stopping the medication, all symptoms began clearing up. Really, I am not prone to complaining or leaving negative reviews, but I do feel there are far better options for your pet than this money factory
