That's called separation anxiety. Bet if you kept puppy in office with you out of
cage, you would have an easier time.
I know a lot of people have cages and have a need to use them,
but I have never used one, nor like them.
There's an item out now called "Thunder Jacket" that does do what it claims,
which is to calm. Or you might need the Dog Whisperer,lol.
Cute pup, You'll have many years of cleaning up after, er I mean many
years of companionship,lol
