New member and soon to be owner

Everyone, i'm new to the forum and soon to be an owner. Just a little bit of background story about myself before I jump into my question. I'll try to keep it short.

So I'm a single child in the family and when I was a kid, my parent got me a black lab (named Frankie) as a campanion. However, Frankie was more than just a campanion, he was a brother to me. Unfortunately, he passed away 5 years ago due to liver cancer When he first past away, I couldn't see myself being able to let him go and get another dog. About 2 years ago, my parent got a yorkie terrier (female and now spayed) My parent just loves her to death and she is a very smart and beautiful girl. However for the past while, a good 4 to 5 months, I've been wanting to get another large size dog. As cute and fun as my parent's terrior are, I still prefer a big dog. There is just so much more you can do with a large dog, IE, hiking, jogging..etc (i tried taking my parent's terrier for a jog once and it ended pretty quick as she got tired pretty fast)

I've done alot of research online as well as talked to different dog owners, I have pretty much decided that a german shepherd fits my lifestyle the most because of their active nature. I'm a pretty active guy, i'm very into outdoor activities. However, I live in an apartment and I work a typical 8 to 5, monday to friday, office job During the day, obviously I can't take care of the dog and a dog like a shepherd requires alot of attention. So my plan is to bring the dog to my parent's place in the morning (only 10mins drive away) and my mom doesn't work, so she is home pretty much most of the time. This way, the shep will get some attention while being look after while i'm at work. My usual routine after work is to go for a jog or a hard run after work and it will just be awesome to have a dog like a german shep. to come along.

My question is, say monday to friday during work hours, I bring the dog to my parent's place. How well do you guys think the shepherd will get along with my parent's terrier? Believe me, my head will roll if anything bad happens to the terrier I know it has almost everything to do with the two dog's behavior. and I know the terrier will get along with the shepherd really well, because she loves making friends and get along with other dogs well just only at times she gets personal with her food bowl.

Any advice or concerns I should know about? Because I found a breeder and they got a litter of pups ready to go at end of august.

Thanks in advance
