WOW! That took weeks!

Assume symmetry. Should fall into place.

I would hang whoever posted this.

It?s a dog. Nice result but you kind of have to make it up as you go. Symmetry in almost everything except the eyes and the top of the ear on the right. Here?s some help to get started.
R1/C8-10,C14-16
R4/C4-5,C9-10,C15-16,C19-21
R22/C9-16
C1/R13-16
C25/R13-16.

Couldnt have done it without those hints, thank you Rats-eijnah!

another little hint: the bottom 5x5 squares in each corner are blank (r18-22, c1-5 and 20-24)

Thank you very much for the tips! It would be impossible to solve otherwise!
