I went through the same thoughts as you.....it is normal. I was all excited for my first pup to have a friend and when he arrived he was absolutely precious but my goodness....the work, the training, the adjustment period for me, for the new pup, for my first pup, & for my cat. I got really frustrated and questioned whether I had done the right thing....it was so simple and so easy with one. I would say it was a rough first 3-4 weeks....then it slowly got better and better. He learned, at a different pace then my other pup but he learned and he is still learning. Now, I can't imagine my life without him and neither could my other pets. They love him as much as I do and I know I did the right thing but just like anything....it's an adjustment and it takes time and patience....LOTS of it. I'm so glad they have each other when I can't take them with me, it is so comforting. And it is one more little someone to love and snuggle on.....I love them all so much....my family wasn't complete until he arrived.
If you truly want another pup, if you really really do.....they I say go for it. You won't be sorry. You will get frustrated and lose sleep and be cleaning up lots of pee and poo but after a few weeks it will get easier and you will be so happy you did. The puppy stage doesn't last forever. Good Luck and let us know what you decide.
