How well would a German Shepherd get along with other dogs?

i think they should be fine

My german shepherds got along well with all types of dogs. It depends on how well they are socialized when they are growing up. Your older dog may not like the playfulness of your puppy at first but they should get use to each other eventually.

We had a German Shepard/Austrailian Cattle Dog mix and he was not a fan of any other dogs. We got a Doberman puppy and had to keep the two separate or watch them at all times because he would go after the puppy even once he got much bigger.

wen my german shepard was a puppy i had a 6year old collie and we was worried that my collie wudnt get on with the puppy or vise versa but they get on fine my collie sumtimes growls at my german shepard even now who is now a year and a half but hes just showing her who is boss and she backs straight down so chances are ur miniature pincer will keep the puppy in its place and the puppy will grow up with respect for your other dog and will learn wat not to do

If well-socialized, then GSDs shouldn't have any problem with other dogs. My girlie doesn't really care about other dogs much, but I use her to socialize a dog-shy Husky pup that my friend owns, who was attacked as a baby.

hmm…
they should get along together with no problem..
the gsd puppy should be fine and wouldn't much need all that attention,
but the dog you all ready have might be the problem..
so that you don't have any, make sure you intrudes then when they are most calm (example: while the dog is taking a nap, wake them up gently) then introduce them slowly (supervise them)

gsd does sometimes doesn't get along with other dogs (if not well socialized) .. but when puppies, they might be scared at first from big adult dogs but they are mostly friendly and playful..

so don't rush the dogs and just be patient and gentle.
let them play just see what the dog's reaction toward each other and don't forget to use tasty treats like cheese so that they know that being with the other dog is a good thing..

but if the reactions are shy or just avoiding each other,
then don't push and force then together!
just lore them together with treats and let them be together in the same room (doesn't have to be close but just in the same room)
might take few days or hours (or minutes) you never know

good luck~

it all depends on how they are brought up

we had a Belgian Shepherd
( a HUGE German Shepherd, 150 lbs)
and we also had a Westy, a rabbit
a chicken, and several cats
he got along fine with all off them
