Although I already knew a lot about dogs back then, raising a puppy was definitely different than I expected it to be. Never ever underestimate the responsibility you take on to yourself when buying a puppy.
If you are looking into resources online that will teach you about puppy training, don't believe that this is what all puppies behave like. Every puppy is completely different and you will run into your own problems along the way.
Everyone knows that a puppy requires a lot of attention and supervision but when I tell you that you couldn't even turn your back on her then I mean it.
Sleep deprivation is a real thing and it's probably the worst when it comes to enjoying your puppy because you will be literally walking around like a zombie.
After those initial two weeks, things drastically got better. Having a puppy is so fun, you will just need to breathe through the hard times.
