Cheese is a great way to teach labs! Everything they do when it comes to training is repetition, with rewards of cheese! Apart from barking, my Lab learned every command by both voice, and hand signals
All by the time she was 8 months old!
Cheese is good for them, less fattening than alot of the treats you can get dogs, and they seem to do anything for it!!
The only other thing ive seen my Lab do anything for was Plauses (not sure on spelling) which are some sort of shelled seafood...Not sure about much info as I dont eat any sort of seafood
