They have a wonderful guarding instinct towards their family and will wander from room to room with you in the house as you go about your daily life. They ARE NOT a dog that wants to stay outside all day - they want to be with you and next to you ..... so if you don't want a dog in the house and beside you this breed is NOT for you.
The Weimaraner is a wonderful family dog and they are usually very tolerant with children but of course regular child/dog common sense must be used. Some have a low tolerance for cats and other small dogs as they are instinctively a game hunter but many are brought up alongside cats and other pets and are just wonderful with them.
Weimaraners need mental stimulation to keep them happy. A good walk, a game of ball and lots of attention will keep them happy - if they are left alone for long periods they can develop bad habits such as barking, digging and chewing.
They are a very smart and cunning dog. Many learn to open doors and stealing food off the kitchen bench is a favorite act of many!
As they are a stongly built dog with an active and headstrong mindset they do require good basic obedience. It's often written that the Weimaraner is not for a novice owner and while I agree ..... it doesn't mean this breed can't be your first dog - it does mean that you need to put in a lot of work. I recommend at least 6 months of obedience training with your Wei if you are new to the breed or dog ownership.
