He's certainly cute- but look a bit closer- he's a minimal dwarf- look at how short his legs are & how large his head is. He's also only about 24 inches tall. The large belly is also probably a sign his organs are enlarged.

Most breeders give these guys away, if they aren't euth'ed at birth. Sounds mean, but sometimes it's kinder, as they have so many issues with their health. We had a Minimum dwarf live to his 20's before the arthritis in his back & legs got too bad. AS this little guy has made it this long, he might have a few good years left with someone willing to address those issues when they come.
