Going the fostering route here would be good, and check to see if your apartment has breed restrictions, but if you are looking for a snuggle dog, check out Pit Bulls. I have had a full Pit, and two mixes. One was 1/2 Pit, & 1/2 GSD (I saw the parents). The other is just a mutt from a shelter who was 2 yrs when I got her, and I have no knowledge of her background, but she clearly has maybe, one Pit grandparent.
Every single person I know with a Pit comments on how cuddly they are. Mine have insisted on sleeping me, and they want to sleep right next to me. Most dogs who want to sleep near you want to sleep at the foot of you bed, or on the floor next to your bed, but Pits have to spoon.
Female Pits can be pretty small. Some are under 50lbs. Even males aren’t particularly large-- they usually are smaller than Labs and GSDs.
Ignore all the hype in the news about how dangerous they are. The problem is that people who want a nasty dog get Pit Bulls, they don’t get Chihuahuas or Golden Retrievers. And because of their size, a Pit bite is more dangerous than a Chihuahua bite: but the fact is, the dogs that bite the most are actually Chihuahuas, and after that, Dachshunds, and Cocker Spaniels. Jack Russels have a pretty solid bite record by percentage, but they’re not as common a breed as Pit Bulls. Also, I read a metastudy several years ago that uncovered the fact that many police officers either could not recognize a Pit on sight, and recorded a dozen other breeds as Pit Bulls; recorded many mixes as “Pit Bull mixes,” when they might have been Pit/Lab crosses, so Pits got “credit” for the bite, and Labs didn’t; and some officers apparently thought “Pit Bull” was a synonym for “vicious dog,” and recorded everything from Jack Russels to Akitas as Pits."
Pits are my favorite breed. My brother, who is as far and away from the stereotypical vicious dog owner as you could get, and is married to a very petite woman, has had three Pits. He’s got an album of “Pit Bulls with kittens” on his Facebook page.
They are active, but you can satisfy they need to move with walks or hikes. They don’t need a big yard to run around. In fact, because they want to be with YOU all the time, they are happy without a yard.
Anyway, when you are fostering, if you landlord permits, consider a Pit Bull.
