Considering these breeds I want to ask that Can you afford the monthly expenses of a dog? Like vaccinations, food, medicines etc. Its a big responsibility when u buy or adopt a dog for the next 10-12 yrs. Since I've also adopted my dog from a shelter so i know that the breed suggested by you are large and not for first time owner if u do not have any exp. with dogs. They cost around 1.5K-2K minimum per month as maintenance. So better to think all these points and go ahead for a pet. Dont mind its my personal opinion. ya, my exp. is that adult dog is better than to raise a pup. Best luck.
