Awwwwwe, your puppies are so cute!!
Both Keiko and Gunther were not used to being crated when I got them. Gunther at 12 wks and Keiko at around 6 wks (I actually didn't want her til 8 wks, but I didn't have much choice, the owner dropped her off early) Both of them cried straight thru the night for about 2-3 nights. I never let them out for the first 2 hrs they were crated b/c I knew they did not have to go b/c they went out right before being crated.
Believe me, it is hard to ignore, and my husband was ready to pull his hair out with Gunther.......
...........but
by the third night, he was quiet, and only whined to let us know he needed to go out...........
........ONCE per night. yay!!
If they know they can get away with it, and you will eventually let them out...........
.......believe
me, they will cry for hours on end b/c they know the end result is freedom, even if only for a few minutes. This too, shall pass. Just remember to be strong, and invest in some earplugs.
