Welcome. I hope you're finding a lot of information.
I don't know the equipment differences between the US and England, but I use the plastic "airline" crate. A big rectangular plastic crate, with a steel door. In the US they run from $100.00 for a petshop brand, to $1000.00. In the house I just use one of the petshop brands. Mine is from a company called Petco. I personally do not like wire crates, but that is just my opinion. Many folks have them, and like them.
First few weeks of having a Vizsla?
Feed what he'll eat, not necessarily what you want him to eat. Have a few small bags of different types, and slowly transition him from what the breeder has been feeding him, if you desire to go that route. If the breeder has started him on a quality feed, and he eats it, Stick With It.
Work on his manners very slowly, and cut him some slack for the first few weeks. he has a lot of info to process. "
Every single time he does something right, make a big fuss over him. When he does something wrong, gently steer him in the right direction. Play lots of games with him. Give him many different objects, of different textures, shapes, and hardness, to chew on. He'll go from one to another and back.
If he displays any inclination to retrieve, Exploit It. Play lots of "Fetch", with every toy he has. This "game" will lay the foundation for so many other things, six months to a year down the line. Most importantly recall. He's naturally returning to you. That's a big hurdle to overcome with some dogs!
Give him every opportunity to get out of the house to go to the bathroom. He wakes up, out the door. He gets done playing, out the door. He comes out of his kennel, out the door. Of he's not actively engaged in sleeping, eating, or playing, he's probably getting ready to go to the bathroom. Get him out the door a lot. Make it a habit, and a pattern, that he can recognize. In a few weeks he'll start to tell you when he needs to go out.
When he goes outside, and goes to the bathroom, be sure to make a big fuss over him like it's the greatest thing that ever happened.
In the US, puppies have a series of shots they get starting at 8 weeks old, and continuing to 16 weeks old. I don't know that I would be comfortable putting my puppy in a daycare service, until he had finished his puppy shot.s This may be different in England, I don't know.
Mostly, let him get to know you, as much as you get to know him.
You'll never beat a lesson into a dog, you just beat desire out.
