I have only one puppy and know I could NEVER handle 2!!! So I'm impressed that you are even trying!
There are tips and suggestions on ---> Should I get TWO puppies/dogs at once?
But I think once you decided to take on 2 puppies at the same time, you also willingly took on that alot of stuff will now take twice the time. So they have to be taken on separate walks, and separate training. Double the puppy classes too unless you have someone that can take on the other puppy during classes for you.
