My dog is almost ten months now and I got him off a neglectful owner at 3 months. She said he was a cane corso and he really net all the specifications growing up till now. I was wondering what you guys think, maybe there is a mix in him, he's fawn with a bit of brindle on his back. I'm questioning his mix bc his head is not as big as I would have thought it would get, will it grow more at the age he is? I know he is going to fill in he is about 75 lbs now and has not even close to filling in! Thanks for any help!
