Bro...Great Danes are awesome dogs!!!
We have one that is about 1.5 years old (May 15th will be the 1.5 yr mark). Attached are some pics of her growing in that short amount of time...you will need some prepping for sure, but let me know any questions you have and I will get some answers back to you. There are a few GD sites that give some very good info on them, send me a PM if you would like them.
Oh, and be ready...for months 2-6 they gain about 5 lbs per week!!
Last, but certainly not least, thanks for your service, and welcome back bro...enjoy the new pup!!
8 weeks old (18 lbs)...BTW my dogs ONLY eat raw...mainly (say 90%) fresh bone-in chicken leg quarters (not the frozen ones from WalMart, shoot me a PM if you are interested in which ones)
3 months:
8 months:
11 months: (my boy is 10 and tall for his age)
16 months: (right at 140 lbs)
She is right around 34 inches tall (which is at the top of female height averages) and is starting to fill out more now. Probably pushing 145 lbs. Like I said, congrats and shoot me a PM if you have any more questions.
