The highest concentration of dog hair extract available, proven in studies to be more effective for diagnosis and treatment.1,2

150 mcg/mL of Can f 1 is 30x more concentrated than the conventional average of 5 mcg/mL of Can f 11

Because Can f 1 can be present in every home (even homes without pets)3, you must have an effective dose for diagnosing and treating patients. Practice parameters recommend 15 mcg of Can f 14; and you can easily dilute AP Dog to this dose. To get an equivalent dose with conventional dog products, you’d have to use approximately 3 mLs per shot. Use AP Dog for an accurate diagnosis, and for great patient care and treatment.1

An effective diagnosis (and treatment) means you reach and benefit more patients. Extracts with lower concentrations could result in false negatives during diagnosis.

Publications, studies, and abstracts have demonstrated the performance of AP Dog for both diagnosis and treatment of dog sensitive patients.1,2

Manufactured using our exclusive Acetone Precipitated (AP) extraction process for maximum concentration and efficacy.

AP Dog is reconstituted without phenol. Phenol can denature the proteins in allergenic extracts5.
