We let our puppy out in the middle of the night to eliminate? Our little guy is almost seven months old and weighs about 35 lbs. The vet says he probably won't get much bigger. Some nights he'll sleep until early morning, but others he'll begin whining to go potty. By letting him out in the middle of the night, are we promoting this habit to continue? Would it be better to see if he can fall back asleep and hold it, or is this a phase that he'll outgrow either way? Any advice would be appreciated.
