Took our 10yr maltese mix for cough that was getting much worse. Diagnosed with bronchitis but told based on chest xray that she had heart disease and heart was 2x size it should be. Was told to visit our vet Monday morning (this was Saturday evening). The ER vet seemed pretty grim about outcome. Spent next hours in tears. Went to our vet. They did new xray because her heart sounded fine and 2 of the three xrays ER vet had done looked OK. New xray showed heart was a 10. The range for this size of dog is 7- 10.5. So even though high in range it is within range and no cause for worries. No heart disease. The antibiotics did get rid of her cough. But all that worry, needless tears and expense for their three xrays and wrong diagnosis.....???? Really makes you wonder about taking your pet there.
