Does my Basset Hound look underweight?

Hello! I am a new basset hound owner. This is Ser Copperbottom. He’s 7 months old, 48 lbs. I feed him twice a day and he drinks a ton of water, lol. I took him for his recent appointment, and they had told me that he is at a healthy weight, but I can’t help but think he looks a little skinny. I’d love to hear someone’s opinion who knows basset hounds, has experience with them and could tell me if this is normal.
