GSD or Rottie???

[Windsor342ci]

Hi guys, without this one flaring into a FPV vs HSV or Patrol Vs Cruiser, Im trying to obtain some advise on a decision I will be making soon.

Too give a bit of background, with the next few weeks my wife and I will be moving into our new property and I have been given the green light to get another dog. We've currently got a beautiful 12 mth old Boxer which has been with us from word go and is perfect.

We are looking at upping the anti and getting a dog with a little more protection background. I have narrowed down to the above 2. Now the property were getting is an acre block so size isnt an issue. My wife has grown up with GSD and through her is my only real exposure to the breed. Me, I have grown up with Rotties. Now we can either get a pup or a male which is already trained up at a reputable trainer I have been referred to. But I'm not to sure as of yet.

My experience with Rotties as a young child was, playful stubborn dogs but like a big brother if you would. Very loving and caring. My little exposure to GSD is interesting, tried to get bitten twice and plenty of aggression! No TLC their!
That being said it wasn't my dog and I was a stranger so I won't hold that against him! I guess I'm a little concerned that a Rottie will be a big cuddle bear and about as assertive as my turtle. I set aside time each day with my dog so it would never be neglected and dog parks religiously on the weekends. I understand grooming wise the GSD has alot more to maintain and both need to have heavy breeder checks done from all the nasty diseases.

A little guidance from any experts.... If it was my choice I'd have both!!!

Thanks
