Oliver is my best friend. I wanted a dog that will do well in an apartment, and I am not disappointed. When I do more I expect no issues. He needs exercise but it doesn't take too much to tire him out, which is just right for me. He loves sleeping under the covers against my leg. He really likes burrowing, and occasionally he tears up the carper if we're not careful, so watch that. He loves playing tug of war and fetch, anything that involves running is also a blast for him.
I take him to the groomer once per month. He doesn't need it very much, being a short hair. But floppy ears are prone to infection so I want to keep them clean, plus it's more socialization for him.
I rated his trainability as "good", because he has a stubborn streak. He potties at pretty consistent times which makes it easy to prevent accidents. He is very independent though, and I wouldn't have him with another pet as he demands my attention.
The person I got him from had him and his siblings sleeping in crates. Oliver is in a spacious but covered crate during the day. If I leave him alone in a large room, he will become pretty upset, and the enclosed crate with his food and water seem to calm him down.
He's not yappy in the least, which was a worry of mine. He only barks if he's in his crate and sees me not paying attention to him.
I love this little guy so much. He thinks he's a lot bigger than he is though, so I've had to make some changes to my place (ie. putting pillows by the bed to make it easier for him).
Highly recommend, as long as you prefer a dog that is more cuddly than playful, and who prefers to have you all to themself.
