Hi Celt-
Do you by chance have any links to pictures of him at the condition you prefer him at vs the condition he’s in right now? This would help in evaluating if he is indeed too skinny.
Also is he getting a lot of exercise? He could possibly be losing fat and gaining muscle which makes him appear skinnier, but not actually be too skinny. Heres an image of an Iggy thats in really good shape; http://www.sighthound.net/dashlookgood.jpg
Does your boy look anything like this?
Also if he’s maintaining his same weight, not losing muscle tone, has a shiny healthy coat, eats well, has energy etc, I’d say it could be that your preception of what healthy weight looks like could possibly be skewed. I think we’re used to seeing overweight dogs now and some people believe this is healthy. It’s far better for a dog to be a couple pounds underweight than overweight.
Heres a great picture of another breed (Pit Bull) that people often think are too skinny and malnourished when infact a dog like this is in peak physical condition. https://k50.kn3.net/taringa/6/7/0/4/A/9/elieceradd/972.jpg
