Good morning everyone. Just curious if huskies have any history of lung cancer or respiratory issues. I have a 10 year old husky that is grunting from time to time when he breaths out.

Not particularly. I have one who has EBP (eosinophilic bronchopneumopathy) and while of the dogs who have it several are huskies, it's pretty rare and usually shows up between ages 4 and 6. It will shut a dog's breathing completely down. Allergies are another matter and it isn't uncommon for seasonal allergies to come on at any age. Labored breathing can be caused by many things ranging from allergies, to heart worms, to something stuck in their nose. This time of year depending on where you are located it could just be allergies but keep an eye out for other symptoms such as coughing, lethargy, lowered tolerance for walks,etc.

The one thing that is not uncommon in Siberians is laryngeal paralysis, also known as wheezers. But typically you would see this when the dog is younger. Is the dog coughing in addition to the symptoms you see? To be safe take your pet to your vet...they should be able to help you out.
