I have a bit of a problem: two dogs, one a daschund, the other a
miniature pinscher.
Installed a doggie door, and the daschund has NO problem going through
it with the
plastic weather shield down. The minpin, on the other hand, will NOT go
through the
doggie door UNLESS I pin up the plastic shield.

How do I get the minpin to go through it? I've tried everything I know
-- coaxing him with treats,
but he still won't budge. I put him through it, and he KNOWS it won't
hurt him, but
seems reluctant to "push" on the plastic shield. I'm stumped!

Can anyone make suggestions?

Thanks in advance!
