Well, but this time, it succeeded in setting up debugWIRE mode:

avrdude: jtagmkII_setparm(): bad response to set parameter command: RSP_FAILED
avrdude: jtagmkII_getsync(): ISP activation failed, trying debugWire
avrdude: jtagmkII_setparm()

OK

So it appears your ATtiny44 is already fused for debugWIRE mode.  In
that case, the command you issued (temporarily, until the next power
cycle) returned it to ISP mode.  Issuing

avrdude -p t44 -c dragon_isp -P usb -U hfuse:w:0xdf:m

as the next command should permanently disable the DWEN fuse again.
