I have friends who used to breed German Shepherds, sayang nga at di pa ako kumuha sa kanila nung time na yun. I got advices na rin from GSD owners too. What confuses me there are two types of GSD: show type and working line. The former is more expensive, the latter is aggressive. Difference? The latter's stance is mataas ang puwitan, parang askal. The show type is pababa, parang may slant. I was advice also to get a blood line from working line since they're more of a guardian dog. The show type are kinda friendly to strangers. For me it doesn't matter as long as it guards the house. I'll do more research and buy a book soon. I love dogs since I was a kid. Na miss ko lang ulit ang presence nila. I'm gonna start with a puppy and train him as it grows.
Don't worry about the food. I have resources for that.
