My Yoshi was 4.2 pounds at 20 weeks. He's now 17 months & weighs 8.1 lbs. However, I think he could stand to lose just a few ounces. His tummy seems a little round lately. Lol. Anyway, I would definitely describe Yoshi as "lanky". I'm attaching of photo so you can see his body structure. He has long legs & a long body. This photo was taken last summer, so his tummy isn't round in this shot.
I also have a Yorkie/Maltese mix. She also weighs 8.2 pounds. However, she is more solid...thicker boned & sturdier. Her legs are shorter. I attached a photo of her as a puppy. I couldn't find a good recent body shot.
Yoshi stopped growing (length/height) at about 10-11 months. Since then, he's gained weight, but his frame has not grown. I'm not sure if he'll go through another growth spurt, but he hasn't in the past 6 months.
Yoshi is definitely more fine-boned than Momo (my Morkie). However, he is not "fragile" in the least. He's fully confident with his body & loves to run, jump & walk on the balance beam. He's actually enjoys brisk activity more than Momo & is very agile. I'd like to think that nature knows how to structure a dog's body so that the body can handle the lifestyle of the dog. I would think that as long as he's not too thick around the middle, that his thin legs would be able to handle his frame just fine.
It's funny, my husband & I were talking about Yoshi's body structure last night. We're both very pleased with how he's turned out. He's a nice, solid 8 pounds & we both agreed that he's the perfect size for us. He's big enough that we don't have to be afraid that he's going to get injured. Yet, small enough to cuddle in my arms
