I just found you today, and I'm enjoying your video, I've liked and subscribed. I live in my airstream travel trailer, 7 feet by 21 feet with my Greyhound, Golden retriever, giant breed Anatolian Pyrenees, along with two tiny toy breeds,all girls and one male cat. My dogs ages are 6 months to 15 years old and we all live in peace. The girls floor space is 6 feet by any where from 41/2 to 6 feet. I bought a twin bed that's has pillows around it. So my whole living floor space is one huge bed that most of the girls share. My little 4 pound Maltese is up on my bed which is also my couch. My cat adores his girls and loves to clean their faces. I rescued my Greyhound off the street at about 6-7 months old, she's now about 31/2 years old and my other two large dogs are 6 months and 16 months so we're still doing a lot daily training and it's going very well. I have a smaller fenced in yard where the 3 big girls play together. I have to keep Willow my Greyhound on a tie out because she's an escape artist. I plan moving into a larger space this summer which is going to be such a luxury I won't know what to do with all that space and I'm sure the animals will enjoy it also. But even that will be 8 feet by 40 feet , so still small compared to other homes. So I can definitely say these dogs can handle small space living. I'm retired so I'm with my girls all the time and I love it
