Wonderful Product! The AeroDawg inhaler has made it possible to treat my 16 year old poodle with inhaled steroids instead of oral medication thus eliminating all the unpleasant side effects. He has dynamic airway disease with collapsing bronchi and thanks to the AeroDawg his coughing has decreased from almost constantly to only a couple of mild episodes a day. He can sleep thru the night and is far more comfortable. I can tell he is receiving the medication and it is easy to count how many breaths he takes. We didn't think he would make it another year and yet here he is after a year on the AeroDawg and doing very well!
