Thank you very much

PROC Transpose with a BY statement and a ID statement ought to work, except that SAS variable names cannot be numbers, as in your shown desired output. If you are willing to have the label, not the variable name, be the number, then the IDLABEL statement ought to work. Example: https://documentation.sas.com/?docsetId=proc&docsetVersion=9.4&docsetTarget=n1t09lqx9e277en16e70gu36...

No need to sort this time because your variables are already sorted, but don't forget to include a proc sort prior to transposing.

What I do as an alternative to labels with regards to numeric column names is add an underscore as a prefix.

PROC TRANSPOSE DATA=have
	OUT=want 
	PREFIX=_
;
	BY DOG;
	ID new_age;
	VAR weight_at_new_age;
RUN; 
QUIT;

[PaigeMiller]

That's a good idea as well
