German Bull SHeperd
Yes bulldog is a compound word. The words are bull and dog.
i don't think so, German shepherd is a breed that makes the 2 best guard dog, so i recommended you if you buy a bulldog or a German sheperd, NEVER buy a German sheperd with a bulldog, they might tear each other into pieces. But it is up to you, that was just my warning, the choice is yours.
Yes
Brindle bulldog
No it shouldn't be capitalized.
You would produce crossbreds, Half German Shepherd and Half Bulldog. Mind you the pups may not be the best looking, having picked up both traits and appearance from two totally different 'built' breeds.
Chre is not a German word
"mit" is the German word for "with".
The word FROM in German is von
The word for is in German - " ist "
The German word for he is er.
