Unusual Albacete dagger for comment

[Sajen]

Hello members,
I have recently acquired this unusual Albacete dagger. It's a type A punal, handle from horn and brass, the blade shows faded engravings. What I never have seen before is the dog head pommel. It is approx. 28 cm long with a blade from 17 cm.
Have someone seen a similar piece before? All other comments are very welcome. The last picture show it together with two other Spanish daggers.
