Genetic testing.
Ask for a pedigree from the place you got it from.
Yes, a German Shepherd, like all dogs, is a mammal.
you can tell someones nationality by their references usually americans look mixed. for example if someone is german and french they would look mixed german and french.
I can honestly say that I have only heard of one way to tell if a German Shepherd is purebred. This feature has helped me in the long-run because I have been with a lot of Gernan Shepherds. You can always tell the German Shepherd is purebred if they have a bump on their snout. Both of my German Shepherds have that. Now I also have a German Shepherd/Belgian Tuevern mix. On her, she has no bump whatsoever. But, I know she would not have a bump because of her mutt-mix. But if I did not know her bloodlines, I would have figured that she is not purebred. I hope this was helpful. P.S. I know this is a very long answer, but I choose to go into detail so that if you need to pass on the information, you can, and be able to show why and how you know.
German Shepherds can be found at your local pet stores and shelters. Many shelters also have online websites that can tell you what kind of dogs are available to be sold.
German shepherd dogs love being with you and they just get lonely when you're not around. They can tell when you are going to leave and they get upset that they won't be around you. I had a German shepherd puppy and he'd get like that, whining and trying to follow you if you got far away from him. It's all right for you to leave, but you should try to leave toys and things like that for him/her, and if it's a young dog/puppy try not to leave for too long.
It is impossible to tell because of the different genes but if you type in Kelpie x GSD you can see for yourself.
About 750lbs...second only to the bull terrier (775lbs)...and people think that pitbulls are strong haha (225lbs)...size matters in this case actually (except for the bull terrier)..Great Dane,Cane Corso,Bull Mastiff,Asian Shepherd,caucasian shepherd and Dog Bordeaux bite force are much stronger then for example Doberman,German Shepherd or Pitbull.tho you must consider that for example Doberman would attack the neck and not your arm (like most of the dogs) and its attack is way more leatel.in my opinion,the most dangerous dog's breed are :1. Great Dane. (if a 90kg dog would attack you,you stand no chance).2. Caucasian Shepherd. (im sure you know why and i dont need to get into detail here.)3.Asian Shepherd.4.Bull Terrier5.Bull Mastiff6.Cane Corso7.Doberman8.Dog Bordeau9.German Shepherd.10.Dogo Argentino.Hope i helped you.
German Shepherd X Great Dane? Who knows. You can't tell an exact age but depending on how well cared for 9-16 years.
I don't know you tell me what it means before my teacher comes near me.i am in 3rd grade and I am 8 years old.
You can estimate by looking at its paws, if they are very large compared to its body then that will tell he is going to be big. As your shepherd gets older you will notice stuff like his tail will drag the floor or his ears will be too big for his head.
It is impossible to tell due to the way the two totally different genes would react. Have a look on Google images to see if there is anything on there.
