Many times CT won't affect a dog till they're older. It will start out as an episode here and there, a few times a week, usually brought on by excitement, and increased incidents will occur during hot weather. In cooler weather, it's easier for the dog to breathe, but then as they age and the cartilage becomes weaker, the episodes occur closer and closer together, until they are having difficulty breathing all the time. They pass from asphyxiation and sometimes heart attack, as many have enlarged hearts due to the strain on their systems to provide oxygenated blood to the body. |
