My vet checked izzy out when I brought up that sound and how she does it mostly if she's straining on a leash or running hard, and he told me she has beginning stages of collapsing trachea. Now toby has started making those same sounds when he runs too... But my vet said its most common in smaller dogs and toby , well, let's just say he's far from small. He was 10 lbs at 5 months, he's 9 months now and huge. So I don't know if it's RS or collapsing trachea with him yet. What's the difference in the sound they make to tell how they differentiate? |
