It was neat to stumble on Dr Cheng’s honour and zpacks address in your latest big problem of Bad mood Connection. Our puppy, Charlie was sold to us with a without fail cough. Two different vets treated him with antibiotics and charged me across $300.00 yet Charlie kept coughing remarkably unacceptably in the early mornings. In the end the breeder figured in view our cub’s diagnosis and sent me to Cheng.
