My friend gave me this dog and told me it's a purebreed doxie. I saw the mom and dad and they were shorthaired black and brown shiny sausages. So i was pretty confident that they had a litter of purebreed doxies. But I really want your guys' opinion. He's 1 month and 16 days old, he's also really bony even though I feed him 3 times a day, but small portions. I've read that pure doxies have that trait but im not really sure anymore.
