thanks Spectrum
Looking at that chart I would agree, probably a four.
The side view photo, such as it is, is the first one in the album. I will try to take another, at a better angle

I haven't got a food bag handy but it is Purina Supercoat Large breed - protein 20%/Fat 10%. From memory it says 5 - 6 cups per day

Woody gets 1 1/2 cups (2 cups if Charlie is not focusing, though I try to watch this) twice a day, with the evening adjusted to accommodate extra treats during training.
And before you say cut out one meal, Woody takes my fingers if too hungry.
