I just brought my beautiful 8 week old mini dachshund pup home. He's so sweet but he seems too skinny to me. When I pet him it seems like I can feel every rib, vertebrae and hip bone. Now, I'm a portly lady so maybe I'm just not used to normal. And he doesn't seem especially hungry even though I offer him kibble every couple of hours. Should I be able to feel his skeleton when I run my hand over him in your opinion?
