Lung cancer symptoms. The early symptoms of lung cancer may be a slight cough or shortness of breath, depending on which part of the lung is affected. As the cancer develops, these symptoms may become more severe or intense. Like many other types of cancer, lung cancer may also cause systemic symptoms, like a loss of appetite or general fatigue.
Medium breeds (e.g. cocker spaniel size) begin swapping over at about 8 months, Large breeds (such as Golden retriever) must stay on puppy food for at least 12 months and Giant breeds (e.g. Great Danes) stay on puppy for for 18-24 months. When swapping the food ensure you do it over 7 days.
When you decide it's time to switch your puppy to adult food, make the switch gradually. Start to wean your Lab off the puppy food and onto the adult food bit by bit, no more than half a cup at a time. On the first day of the switch, you might feed a cup and a half of puppy food and a half-cup of adult food. On day seven, you might feed 1-and-a-half cups of adult food and half a cup of puppy food.
