Great Dane care and training

I am researching on how to do 2-year old great dane care. I know dog care differs depending on the breed and age of the dog. My dog is two years old and I would like to know more on how to care for him. Any tips?

I would also like to talk to other breeders/owners who are into great dane training. I am planning to enroll Danee into obedience training soon but I would like to jump start the training at home. Any tips from great dane trainers out here?

Thanks in advance!
