I have a question. Is this kind of like hypoglycemia? I am wondering if this is not heat stroke or something similar, why does it make a difference if you run the dog under cold water or not? I have had this happen many times when training and I always do the same thing but I am wondering if it is necessary or if this is just a response to make sure it is not heat stroke. As far as your question the answer is pretty obvious. Whether it is EIC, hypoclycemia or what, you more then likely have a dog that could very well be carrying a gene that predisposes him or his offspring to this condition. I have been breeding for 25 years and about the best thing I have learned is, it simply isn't worth it to take risks when breeding dogs. You, your customers, and most of all the dogs are only being put in a compromising position. Just my opinion anyway, but I don't think there are too many of us that would willingly purchase a pup from you if they knew one of the parents had this problem. It is most important to protect your breed, your customers and your dogs if you are going to start breeding. There is much to be learned on genetics alone before even considering starting a breeding program. I don't know what level you are at but.....be careful when bringing new pups into the world. Any genetic defect you pass on through your breedings are multiplied hundreds, if not thousands of times over by people who do not know this problem exists in their line if you use your dog for breeding. Sorry. I hope everything works out for you..
