YOu need to start immediantly with basic obedience. You could take a class or you could read a book, whatever you do you need to be the one in control. Right now your dog is. A leash, a collar, and several short sessions a day where you make training fun, but you also be persistant. I grew up working in a kennel and the best thing my old boss ever taught me is never give a command you do not enforce. I would put her on a leash to start with and keep it on her as long as she is around people. Start with sit and down. When people come over you have her on a SHORT leash and you put her in sit and down. You make her stay there. You reward her for good behavior only...that is where i would start if i were fostering.
My pointer VIc came with every bad habit imaginable and this is exactly what i did.24-7 i demanded a certain behavior. I also understood that he was very young and excitable. I didn't expect miracles right off and yes making him down was exhausting but my mother is 80 and i certainly couldn't have him jumping all over her or my grandaughter. Jumping up, climbing up on people, clinging to people was All he wanted to do. He was post stress and desperate for affection and attention. I used t-touch (tellington touch) when he became confused and uncertain of what i was asking him to do. He was stubborn and muleheaded but i can be more so. Consider this breaking you in for parenthood. Dog training and toddler training is about the same thing. IF your dog yawns when you are working her it is because she is confused. Learn to read her body language too. There are a zillion good training books out there, the hardest part of all is getting people to DO it and be consisitant.
Tell your husband training doesn't cost a dime, it takes some study, bucket loads of common sense and your time.
IT is never necessary to isolate, (actually that does the absolute opposite of what you want in the end) to strike, kick, or slap a dog in training. Shock collars are a human crutch for lazyness. Keep that dog under your control at all times until you don't need the leash. Once she understands what is is you don't want her to do and that you will redirect her to what you want with love and affection she will gladly give you her best.
A stern NO with a deep voice, and a frowny face, i use hands on my hips so my body language is easy for them to read will get the message across. The only time a shock collar was ever used in our field training was for dogs that ate the bird instead of bringing it back. Period.
Always make sure your dog has tons of exercise. A tired dog is a good dog. if Victor is being extra stubborn it is almost always because he hasn't had enough run time. Since he is an english pointer he needs more then the average dog.
You CAN do this.
forgot to add..i find using treats to train to be defeatest in the long run. The last thing i want is a dog refusing to do what has been told because i have an empty hand. Love should always be enough. Sitting pretty is my one exception.
