I have been dealing with some issues regarding my female Husky (2) since she was young. She has had some health issues due to bad breeding and genetics, but I have always been curious about her trachea. She used to make this high pitched constant squeak when breathing after pulling just slightly on a collar, with any pressure on her trachea. I used a harness until she got the hang of loose leash training and now she’s fine, on the rare occasion that there is pressure she will squeak again. She has also always had super labored breathing with minimal exertion like playing, or with the heat. I don’t take her out in the heat much but she has a cooled pool when outside in the yard when it’s hot, and has to come in after about 15 minutes. After even a quick bathroom break in the heat, her gums turn bright red, her tongue red and swollen to the side, she lays on her side with labored heavy panting. All of the heat stroke signs and it worries me that I’ll never be able to tell if she were to have an actual heat stroke. Today I took her on a hike; it was 85° out but we only did so for about ten minutes, a fully shaded trail with wind and it seemed nice. She was fine, no heavy panting until I got her home. Gums were red, whites of her eyes bright red (happens frequently with slight heat or playing), etc. Kept collapsing like super tired dogs do in her side. Thing is she wasn’t panting at this point, and seemed cooled off, no heavy breathing. Does heat stroke/intolerance occur frequently in dogs with a collapsing trachea? I spoke to her vet with my concerns over a year ago but she took it lightly. They said her trachea looked well when they tubed her for her spay, is this an accurate way to rule out diagnosis? I am going to request an X-ray I think. Thanks!
