German Shepherd Q&A
Dogs do tend to b more hyper than females but sometimes getting them castrated can calm them down a little. Either way they are both pretty much full on until about 2 year old.
When picking your GSP make sure you stand still and let the puppy come to you. We did that and our GSP was the only one that came up and sat right in front of us, the others were running around like CRAZY!!! Our GSP has a great tempermant and is for the most part calm. We do however Run him for 30 min x 2 per day, and he also gets free run of the yard. Its all about giving them the proper excersize.
