I have a Weimaraner. He's only 11 weeks old and he's been great so far. One of my best friends has 2 of them and i know a couple other people that have them. They are a high energy dog, so if you aren't willing to walk it and play with it everyday, then don't get one. Mine is great so far. He's a puppy and does all the typical puppy things. But they are realy people dogs. They have to be kept inside because they are love their owners and love to be next to them. Some would say they are high maintainence, but i would say they are well worth any effort you put into them. I dont' consider it maintainence, as any dog is gonna need to be trained and played with. But it will probably never turn out to be laid back like a Golder Retriever. Like i said, they are a very people loving breed. The friend i was talking about that has 2, one of them is over a year old and he's great. Protective(barks) but will just lick you to death once he figures out you're friendly. Really smart dogs. If you are considering, please read up on them. Too many people get them because they "look beautiful" and they're so cute when they're puppies, then they turn into a 70-80lbs hyperactive dog and the people give them up. So sad. I guess this happens in all breeds, you just have to know the background and temperment of the breed you're getting so you can train it better, so then it won't turn into that hyperactive crazy dog. If trained properly, they are wonderful dogs. I don't want to sound mean, it's just that i hear about so many people that end up giving up these dogs just because they were uninformed about them. Mine is pretty much potty trained and crate trained at 11 wks and can sit and lay. I wouldn't call him very very high maintainence at all. Then again, he's only 11wks old and i'm still learning with him. Maybe you should just read up and figure it out for yourself. I'd highly recommend this breed, cause i've known them and been around them, but you have to know about them and thier tendancies. as far as their health concerns, not any more than any other dog. Bloat and hyps are the main concerns, but that's with alot of breeds. Here's a few links to learn more about weimaraners....hope you enjoy!
