RE: Lab training
My favorite is Retriever training for the Duck hunter by Milner. Easy to read, uses a detailed step by step approach that can be followed and always worked for all my dogs including pointers. At the very least it shows how to train for all the basic obedience things.
Go to Amazon and do a search there. Wolters is pretty good and has several books. There are a lot of them out there and I bought many of them. Some better than others but with each book you get some knowledge about how different trainers work. Each dog in my experience presents some challenges that might require a different approach so the more ideas you have the more likely you might figure out which one will work.
