Gothic dius and daur

I know that Proto-Slavic *uxo, Gothic auso and English ear are cognate by Ruki sound law and Rhotacism

I know that Proto-Slavic *duxъ (breath, spirit), Gothic dius (wild animal) and English deer are cognate by Ruki sound law and Rhotacism

I know that English deer for semantic development compare Latin animālis (“animal”), from anima (“breath, spirit”).

I know that English window for semantic development compare Gothic augadauro

I know that Gothic has iu / au alteration diups / daupjan

Could Gothic dius and daur be cogante by Rhotacism ?

I mean could Gothic daur has "to blow" meaning ?

Also I want to add that Gothic dius is attested only in dative plural form
