Did that work?
His head looks too big for his body, because he's pretty skinny. The second photo is him meeting Mish
I have no idea what his pedigree is, I'm thinking about tracing his microchip back to his breeder. I think his breeder should know what's happened to him.
He's 18mnths and very big. Not sure about his weight, I know he needs to put some on. He was neutered yesterday so they would have taken his weight for that.
The day I met him it was about 104 degrees so he didn't do much. He smelt Mish (my husky) and she initiated play. He growled a lot and danced around by didn't chase or be rough with her at all. After 5 minutes he came over and put his head on my lap. I felt him all over, to make sure he wasn't shy about handling, and he closed his eyes and leant all his weight on me.
I know little about his drives, but I plan on doing some tests on Friday when I pick him up.
The owners of the rescue say that they've had him with a bunch of their social dogs and he was, as you said about Valentina, indifferent. Unless they initiated play he just milled around with them.
When the owners surrendered him they said he was the perfect dog, but I'm not taking that on face value. They get told that a lot, it's almost never true.
Your dogs are all absolutely gorgeous! Valentina should be a doggy model. I love that you haven't had her ears cropped
I plan on putting on some progress reports with Mack on this forum over the next few months.

It worked and he looks very nice from what I can see

He reminds me a lot of Valentina and doesn't look terribly under weight in those photos. I can't wait to see more pics though once you have him.... he looks like a handsome animal. I know Valentina had gone through some disproportionate body shapes as she grew... at first the only thing people ever said when the saw here was "gosh her paws are huge." That transitioned to "wow, she's going to be really big and strong" as she started to gain weight around 4 months old-7 months old. The next stage was the "why is her head so gigantic" phase. It got to the point that it was just predictable that all the comments would be about her butterball sized noggin. Apparently her body stopped growing and she was devoting all her growing energies to her head for a while. At about a year that tapered off a bit and now she's starting to look a bit more balanced. By 18 months I'd think he's not growing too much more but if he's been underfed he may still fill out. Though corsos are a mastiff breed, don't think that they will get gigantic. A good description would be something along the lines of "the strongest boxer you've ever seen"

He isn't super underweight, just lacking muscle
LOL, I think that description of the transitional phases should be included in the Corso book haha
I've been having trouble describing to people what Mack looks like, and he does look like a big boxer so I think I'll steal that little description from you

I'll keep you updated on his progress!

I have a 6 yr old cane corso. We've had her since a puppy so she is good with dogs, cats, bunnies, chinchillas etc. lol. She is pretty lazy other than her bouts of running around in circles like a lunatic for about 30 sec. I run with my dutch shepherd and when I make her go she lags behind, especially in the heat. She is pretty confident, an absolute suck and pretty needy and always wanting pets and kisses from us, not so much strangers though. She really only barks if she hears someone at the door or if someone approaches her in the car. She does a little woof/growly thing when she wants attention. she is a great dog but not for someone inexperienced or someone that doesn't want a clingy lazy dog. She is about 90-100lb and everyone always says she small for her breed. She is obedient but in all honesty not very smart. The rescue we got her from said her sister had become fear agressive, so I think you need to be firm and socailizing them a lot and not letting them have their own way all the time. This is my experience only and of course all dogs are different and individual. I love the breed and will get another for sure.
