My puppy went from a little thing I could still (sort of) pick up right to full size, no stopping in between. So the medium-sized harness and puppy gate I bought are now useless. - Top Paw® Mesh Dog Harness, bought for $22 at Petsmart, selling for $10.
- Wood, position & lock baby/puppy gate (expands from 26” up to 42”), bought for $19 at Target, selling for $5.
Buy both together for only $12, and if you buy both, I will even through in one free roll of poop bags.
