Training new puppy with first adult dog in the house

[ellephant]

I plan to get a puppy of the same breed as my current DDog, as I want her to have a companion for when we are out of the house.
However, I'm concerned about the logistics around crate training/toilet training the new puppy, when DDog is free to roam the house as she is toilet trained and house trained.
I worry that a puppy may become upset if crated and can see adult DDog roaming?

Can anyone share any experiences of training their new addition while already having a house trained adult dog?

Firstly are you quite certain your ddog wants a companion?

Firstly are you quite certain your ddog wants a companion?

No, I cannot be certain of this. But she's very sociable and as pack animals I believe that ddog would be happy to have a companion, especially during the times when she would otherwise be left in the home on her own for a few hours? Obviously I could be very wrong - she's quite happy in herself and won't fuss if she sees we're leaving the house. But I always revert to thinking perhaps she would still like company - hence my consideration of adding another dog to the family

Do you actually want another dog? Because they might not get on.

That said, I've introduced 3 puppies to resident adult dogs. We don't use crates (don't like them, can largely dog-proof the kitchen) but we do allow the adult dogs time away from the chewing, pooing mini-monster which is good practice for said monster to learn to cope alone.

Most of the time they are kept together on hard floors (which is where the adult dogs spend most of their time anyway).

As for first intro of older dog and puppy, IME it's best done on neutral ground like a friend's garden. Give them 20-30 mins depending on how long older dog is taking to warm up, then take them home together.

Just read your second post and my very sociable young bitch took to the next puppy within minutes and they are best buds, love each other's company, sleep together etc.

We had an anti social ddog and got a dpuppy. Instant friendship. As a dc we had an amazingly friendly ddog and got another. They never bonded at all. In over a decade they simply tolerated each other only. Still worth the risk of you want 3 ddogs. We now have 4. Sadly lost ddog 1 this year.

I find training a puppy easier with an older dog. The puppies tend to just slot in with the older one in my experience.

We use the same method for the puppy as any other dog, outside to the toilet and lots of praise but the puppies generally go where the adults go.

I don’t crate but I do teach the puppies to be okay alone, training and walking separately so they gain some confidence by themselves and I’ve not really had any issues.

Thankyou all,
l crated my ddog initially which I found useful for toilet training. She no longer has the crate, so upon reflection I don't think I would reintroduce one to use with puppy.
As PP suggested, I think teaching puppy to be independent and walking separately etc. will be the way to go to start off with.
I will probably let them both have the downstairs. Hoping that any puppy mischief that might typically occur when left alone wouldn't happen quite as much, because of the company from ddog.
Or at least I can dream!

@ellephant I have never crated any of my dogs. Puppy proof the rooms your puppy will be going in. Get plenty of toys and chewy things. I used puppy pads with mine. The older dog just ignored them. I got a 6 month rescue pup a couple of months ago and introduced to my older dog. They got on great. My pup was not toilet trained. They got on like a house on fire. I'd say the only issue I have is the pair of them racing round the garden playing non stop.
