Here`s another great article:
So I have a 6 month old puppy and I live in an apartment. There's a VERY reactive dog on the first floor who is always barking, and over the past two weeks my puppy has gone from barking in the stairwell right beside where that dog lives (I started avoiding that stair well)…to barking in every stairwell…. To now barking up and down the hallways and stairwells until we get outside or in our unit.
Any tips how to stop this?
