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.
Feeding will normally take place every two to three hours for puppies and they are unable to eat solid food until they are at least four weeks old. Puppies between four and eight weeks can eat a mixture of dry food and milk and then they can shift to solid food completely after that period. If the mother is not present then it is recommended that you contact a veterinarian for an acceptable substitute for her milk as human milk is not appropriate for puppies.
