That is awesome you're getting 2.... I have litter mates and they are both 1 yr 5 months now. It was very hard and a lot of work having puppies at the same time, but totally worth it. We work full time, but we staggered our shifts so that the dogs were never crated longer than they could handle. We just did everything in tandem. For potty training, we set the alarm during the night and brought them outside every 2 hours, then every 3, then every 4,etc. yes we were super sleep deprived but I can say with 100% certainty that these dogs are housebroken. I trust them absolutely. Just keep an eye on them and you will know their signals.
They are the best of friends and I have never regretted having two. They get into trouble together, but they are so funny.
They went to puppy school, and an invaluable suggestion was to make sure to separate them from time to time. This was very hard for me, i.e. walk them separately or take one for a car ride and leave the other at home. Thank goodness my BF was strong enough and calm enough to practice this, because when my boy was 10 months he had to have luxating patella surgery. Layla wasn't happy but since she had been apart from Wilbur before, this was much less stressful for her, and for him. For 2 months we had to keep them separated (to prevent rough play etc) until Wilbur was strong enough.....he was baby - gated and confined in another room. So it was good this wasn't their first time being physically separated.
Good luck and keep us posted!!!!!
