A heavier side of 4 imo
Depends what scale, if you are 1 to 5, then I disagree, the cob is not overweight, though photos are not the correct method to use.
If it is scale 1-10, then cob is not underweight.
agreeHe is obviously lacking in muscle especially on the shoulder and second thigh but topline is not bad, I think he looks fine, not over or under weight just ready to build up properly with increased work then the tummy should lift and he will look totally different, I wouldn't want any less weight on him as I think it would drop off his topline and he would look weak, if you clipped all the hair off he would appear considerably leaner.
I don't think he's overweight....just needs 'tightening up'.
All those responses have demonstrated how unsatisfactory it is to try and do it from photographs - for one thing you need to palpate IMO, over ribs, crest, tailhead and any gutter
I think he looks fine.
