I haven't done a lab in a lot of years but as I recall I started them very young on simple obedience. A lab that doesn't mind is an out of control dog. I'd start with learning to walk on a lead, to sit and to come when called. Probably be a good idea to get yourself a 20' check cord too. 1/4th tight woven nylon and tie a brass snap on with a bowline knot. Gives the pup 40' to play in. When the pup get bigger, maybe three to three and a half mos, up the cord to 3/8th.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
