Rehoming Male Boykin Spaniel puppy

Bo is a registered Boykin Spaniel puppy. He's got his vaccines (requires rabies). Quite enthusiastic but soft and very hard to understand, please. Will make a great dog or a great buddy. Get along with other animals and people. Is used to a crate, but with potty training is not steady. I'm asking for $750 and it's a firm price.

I really hate getting rid of my lovely boy, but I'm living in a studio apartment and moving across the country. Would love to take him with me, but he's already reaching the weight limit of 20 lb and he's just not the dog of an apartment.
