My girlfriend just got a new puppy and we're trying to figure out what to expect as far the size of her puppy when it's full grown. Her puppy is a female, it's 75% neapolitan mastiff 25% pitbull. The puppy's dad was 100% neapolitan mastiff and the mom was 50% neapolitan mastiff 50% pitbull. I saw pictures of the parents and they were pretty big, I would say the dad was easily 100lbs+ and the mom had to be at least 85lbs. I know that size mostly has to do with genetics and nutrition, but I was wondering if anyone could help me with an estimate of the height and weight we could expect her puppy to be. Also, would that be considered a ban dog or just a mix? And what should be the appropriate growth rate for a puppy like that? I would also appreciate advice from anyone who is willing to give it.
