weight VS size..

[wyz]

Hi,

I wanna breed my BP this year (1st time).

I know my female is ready she's a huge girl, but my male is younger and small for is age.

I heard the ok weight for a male is about 900 gr, but I don't have a scale.. Can someone tell me how wide (girth) and how long 900gr is approximatly on a BP.

Thanks.
