Help needed to ID 3 German? medieval coins (Vierzipfliger Pfennig) [решено]

Hello,

all three are very worn and show little chance for an ID but Im still hoping someone here might know.
All three are I believe German or Austrian silver Pfennig coins.
So called Vierzipfliger Pfennig.

Anyone who can help me ID these even with so much wear?

1
Metal: Silver
Diameter: 14.3mm
Weight: 0.47g
Only detail I can seem to make out looks lick a duck.


2
Metal: Silver
Diameter: 13.1mm
Weight: 0.77g
Bird or winged figure?



3
Metal: Silver
Diameter: 16mm
Weight: 0.63g
This one looks a bit mysterious, I seem to see a Dog turned left with plants growing out oh its body.

Thank you,

Paul

The third one might be Bayern-Landshut as they have dogs in front of trees or flowers :-)

Is Landshut really symbolized by a hat? Sometimes, medieval coins are really pictorial.

Thanks Silberschatz, the third could well be from Bayern-Landshut I sent an ID Request on a German Forum and will update here if I got a positive reply.
