Dog Obedience Training For Your Pet Dog

I have a martingale dog training collar for my dog, I got the right size and all, but I am not sure where it is to sit on the dogs neck and that kind of stuff so any help would be appreciated.
the martingale dog raining collar I got has the partial chain on it, so does it matter where that DRing is for the leash to go on? Oike am I pulling to the side or straig twards me if the dog is on my left?

You know the ones you use to house train a puppy, he is a terrier and pees everywhere anyway.
I’m talking about my 2yo son. My dogs were toilet trained by 8 weeks old, come on get with it.
Lenna, no need for the stars, I can figure out what you wrote there. I am not a moron I am university educated just having trouble toilet training my child. How about if you don’t like my Q don’t answer it.

OK just got a dog on the weekend nad she is great so far but can use some basic training?
Treats or no treats to train? What is eveyone opinion?

I’ve had her for a week and I’ve even bought her the puppy training pads, but all she does is tear them up.

How do you train a puppy to go outdoors and what do you do when he does indoors after being let out. Appreciate all the help with this and also if someone has good training to train puppy quickly on chewing and biting.
