I would love to see Ruby and Castle's (beast!) growth charts!

Neobull, I wish I could get a stack like that!

Mason's due for his weigh in tomorrow. He was 23" tall a few days ago.

Mason's growing at a rate very similar to Junior. Ak - Do you think Junior will get much heavier? Mason's breeder was hoping he'd end up around 130. Do you know how tall Jr is?

Neobull: I have a friend with a mystery mastiff mix (DNA test says 50% neo but I don't see it). Her girl was 60lbs at 6 months and grew up to be 120#. (Actually 140 now, but close to obese at that weight.)

Branka isn't a runt! Junior's just a tank. :)

BB, Junior's parents were 150# a piece (dam was weighed after the pups left and she still had a little extra weight on), and the breeder thought Junior would be larger. Sooo, yeah, he's going to be on the big side. I don't have a height on him yet, I'll try to get it this evening though.

He is 25" for the short amount of time I could get him to stand still next to the wall while putting a "toy" on his back. :)

And I screwd up on his parent's weight, they are 140.

Branka's growth (She's by far the smallest of the 6 littermates of hers I've been in contact with!) Neapolitan Mastiff x Bullmastiff female:

11 weeks 21lbs (right before I got her)
4 months 40lbs, 17.5"
4 months 2 wk 45.8lbs
5 months 53lbs, 20.75"
5 months 2 wk 57lbs
6 months 63lbs
6 months 2 wk 68lbs, 22"
7 months 74lbs, 23"
8 months 79.5lbs
8 months 2 wk 81lbs, 24.25"
9 months 86.5lbs, 24.5"
9 months 2 wk 88.5lbs 24.75"
10months (tomorrow) 92lbs 24.75"

Branka's a little over 10.5 months now and weighed in at 96lbs today. I'll try to measure her later to see if she's grown in height at all, doesn't look like she has to me...

Woo Whoo! I think she did get a little taller... I just measured her 2x at 25" :) Hoping for at least one more inch in the next 8 months! 26" and maybe 120lbs seems like a respectable size for a Mastiff :) Clearly putting her out of the "Is that a Lab/pit? Lab/Boxer?" questions I hope.

Ruby's high in the rear too. And Ruby has NO angulation in her read legs. It's almost painful to watch her walk. However she's by far the fastest & strongest of all 4 of these guys. So I don't care. Your girl is still pretty young; she might straighten out.

Thanks for the bump! Mason has a weigh in tomorrow too. It completely slipped my mind last Wednesday. I think 26" is a nice hieght and am hoping for 26-27 for Mason.

He was a lot taller at 6 months than Branka so I doubt that will be a problem!
