Hi, pup is now 12weeks old  at night he takes himself off to the kitchen and goes in crate around 730-8pm at night which is great. The issue is i cant even go to the loo in the day i need to crate him so he doesnt get into trouble or pester the older dog but he screams and i mean screams the place down the second i leave the room as soon as i move off the sofa hes up watching  my concern is if i leave him to cry like that he will hate the crate and refuse to go in at night. Meanwhile im stuck in the house so he doesnt scream the place down hubby works night shifts permanently and comes in the door at 5am from then hes off and up  and then im up for the day but cant do much.
Ive done the treat and move further away from crate  as soon as out if sight the shrill noise and he dont settle enough to go back in and treat please any advice will be highly welcomed.

Have you done any actual training with your puppy? Apart from crate & toilet training?

Sounds like your puppy needs some brain stimulation, to calm him down & teach him some acceptable behaviour.

Puppies need to be taught a miriade of behaviours & separation is one of them.

Special toys that are only given when the puppy is left  like filled frozen kongs, can reward him when he is left.

Puppy training

What about a baby gate so they can be kept separate without the need for crating?

Mine have just come to the loo with me until they understand that I’m not going for good and will be back in a bit.

For how many weeks have you had this puppy now?   It sounds to me as if his temperament isn't as strong as it could be.  My puppies, usually a pair, NEVER acted up like that if I happened to do something like going to the loo.  And as most of the homes we lived in when we had puppies, had an upstairs bathroom, so no way could they be coming up with me.

I think you are, with respect, making much of all this.  Yes having a puppy involves the huge demands a puppy can make, but looking at all your perceived problems, it just looks like normally puppyhood.

Calm down dear.  Try to inject a bit of enjoyment there - puppies grow up fast, so before you can blink, his puppy days will be over.

mambas, my first weimaraner was like this. gave us 6 weeks of hell first 6 weeks . rock solid temperament, not fearful but very very loud when was not with me first 6 weeks.  we did all the things, the chew to play with while I sped to the toilet, the not reopening the door until racket had stopped. the training and entertaining. It was like she could manage with 0 sleep.  I couldn't.  My husband also worked nights and it really was hell those first weeks.    thankfully she eventually got the idea.

our second weimaraner and whippet were pretty good within a few days, I am sure they were just as worried /unsure but they were nothing like as vocal. all pups are different

It doesnt sound like youve very much with puppy other than crate train and toilet train. I would be working on separation anxiety. Like standing the other side of a stair gate , reward for quiet and then go out of view and straight back and reward, increasing the length of time out of view.
Id also be working on brain games. I know puppy is only 12 weeks but have you been taking him out with your other dog? you can carry him or put him in a baby sling / push chair so he gets mental stimulation.
What commands does he know now? Maybe work on teaching something new each week.

Yes follow claire’s advice and the person above who suggested a baby gate! I have a 12 week old lab, she doesn’t have any meals in a bowl, she eats her meals during training sessions, she may be a bigger breed than yours but you can still do lots with her. Take her out to a cafe/places in your arms…you do not have to be confined to the house, surely you got the pup to be able to enjoy life with so do just that!

We had a period where she would cry a bit when I left the room, especially because she was separated from the other dogs too. The problem is the less you do the more he’s going to react when you do actually have to do stuff or leave. As Claire suggested get her brain working throughout the day with training, lickimats, taking him out etc. That way he’s mentally going to be very tired and in need of a sleep, invest in a baby gate (you can get them for free or dirt cheap on facebook marketplace!) and get him used to you leaving. You need to start off tiny and small, almost as if its not worth it (but it will be!). You can also get him used to a cue for when you leave that lets him know you’re coming back. There’s always ways you can improve the situation but it does take work.

I do 4 x 15min training sessions a day

That is exactly what i do he only gets special chews and sweets in his crate

Believe me i am doing all the training even separation moving away and then a bit further as i said in my post. It looks like i will have to get hubby to wear earplugs and try to manage on even less sleep than he already gets working 6 nights a week.

Thanks for the advice he is well exercised i crate all his naps and as soon as i potter around hes up! I will need to just let him cry as loud as he is i just didnt want to make him hate the crate and then have issues at night when he is really good.

15minute sessions are quite long for a little pup his age. If he’s asleep then get up and do things like you are doing, eventually he will understand you getting up and doing things isn’t bad and he’ll settle. I’m assuming he won’t scream whilst you’re in the room so at least you’re able to do that, and do do it as it’ll only help when you then need to leave the room etc, if he gets used to you getting up and doing things whilst he’s in the same room as you and he can sleep then he’ll be able to progress from that and be happier than he is now with you leaving the room. There’s no need for your pup to be screaming, and its my opinion if he’s really getting that worked up about it then leaving him won’t be helping whilst he’s in that state, it’ll only reinforce his feelings, which sound as though he’s distressed. You’re better off starting right from the beginning and literally standing in front of the gate and giving a treat, then stepping a couple feet back no noise and treat etc. And taking it slow, it may even take a couple days before you can even get out of the room for a second without him making a noise but it will help in the long run by taking it slow. If you’re doing this training with him then I’m assuming you’re teaching him the basics of sit, stay, wait, down etc. The other option you can do is use this training and use his cue for wait, go and treat. If he’s learning what it means then he’ll be able to hold it at least for you to go a few steps away, use the training you’ve done with him to your advantage.

Is there a radio on when you are out and hubby is in bed?
MAybe try a snuffle mat in the crate or whereever when you need to leave the room. at 12 weeks old 1 hour training a day may actually be too much? This little one could actually be over tired escpecially if youre saying she gets lots of excercise, bearing in mind she should only be just about starting lead walks for 15 minutes per day?

Perhaps its time for a vet check if shes really that bad?

Assuming the Cav side of her parentage is SM/CM clear? Bichon side may be the issue with separation / vocal etc

I assume when u are training u are using treats as a reward each time he does what u want ?
Also don't forget it was only a very short while ago u couldn't get him  to settle in his crate at night  sounds like that has changed for the better so that's a positive. 
There is some  really good advise given in other posts . I cant say I had regular training times with mine but did small bits randomly throughout the day as the chance occurred.

Yes im using treats as rewards :) im sure it will come im not worried leaving him to cry like i say my worry is he will then hate the crate thats not what i want :( thanks its all taken on board. :)

Yes i already have an older bichon he can be like that too at times not very often now though i will give a snuffle mat ago i tried kongs/treat balls etc as soon as he realises im not there hes off i am persevering with the crate step away then treat if quiet ive got as far as out of the room for around 30seconds back in and treat i will continue this and hopefully there is light at the end of the tunnel.
Thanks all

> out of the room for around 30seconds back in and treat

Thats a great improvement, you'll just have to learn to pee really fast .

If he is ok in the crate (door shut) when you are sitting right next to it (for an extended time - like you are reading a book or working on a laptop) then the next step is you staying in the same room but moving away from the crate. I do this in the kitchen, so I would be loading the dishwasher, cooking or prepping meals, cleaning, etc etc. Only when he is ok with that, do you start to leave the room... and then it's best to do stuff in another room which makes noise so he knows you are out there, he just can't see you.

How much sleep is this pup getting? They need roughly 20hrs of sleep a day when young. At 12 weeks no more than 15mins formal exercise. Need a lot of socialisation and short training sessions.
A lot of puppies need enforced rest and learning to settle in some pups and certain breeds is essential. They aren't easy puppies and they rest our patience to no end. I always say if they weren't so cute many of us wouldn't want a puppy lol
