Since we can't see them, how do they look to you? Can you see ribs, do they look like sausages or are they somewhere in the middle?
What does your vet say about their weights? Just for giggles every once in a while I take the boys to the vet to weigh them on the scale. What this does is twofold. They make a trip to the vet without any drama and the office people will give me very candid opinions about how they look. Best part is ...it's free.
If the Bassett is less active than the others, feed him a little less. If the others are so active they look a little thin, feed them a little more.
My guys (2 GSDs; 1 weighs @ 70, 1 @ 100) are constantly monitored. Chazz is older and he's slowing down so I've cut his food ration down gradually to where he lost weight and he's now maintaining. Buck has maintained his weight pretty consistently for a while. Once the weather gets bad and they can't go run regularly, both will have their rations cut back to keep them from packing on the pounds this winter. Wish I could do the same for me - but it never works!
